The United States has ordered non-emergency government employees and their family members to leave diplomatic missions in Saudi Arabia as Washington responds to a rapidly deteriorating security environment across the Middle East, while a new U.S. intelligence warning says Iranian efforts to target American citizens and personnel have increased sharply and that some lethal plots have reached what officials describe as “advanced stages.” The measures come amid renewed attacks by Iran-aligned Houthi forces on Saudi airports and energy infrastructure, heightened concerns over possible Iranian retaliation against American officials and facilities, and fears that the wider regional war could enter another dangerous phase.

The most concrete new evacuation measure was announced for Saudi Arabia, where the State Department ordered non-emergency U.S. government employees and their family members to depart following a succession of missile and drone attacks. State Department spokesperson Tommy Pigott said the ordered departure applied to personnel in Saudi Arabia, while U.S. officials told Reuters that family members at several other American diplomatic missions in the Gulf were also expected to be withdrawn as security postures were reassessed. The department did not publicly identify every mission affected by the additional measures, making it important not to describe the entire region as being under a single blanket evacuation order.

The withdrawals gained greater significance after Reuters obtained an October 23 memorandum from Director of National Intelligence Jay Clayton warning Secretary of State Marco Rubio that U.S. intelligence agencies had received information indicating that Iran had substantially intensified efforts to target American personnel. CIA Director John Ratcliffe was copied on the unclassified message, which said lethal Iranian plotting against U.S. citizens had reached advanced stages in the Middle East and in certain countries outside the region.

The memo did not publicly identify specific intended victims, locations, operational methods or timelines, and U.S. authorities have not announced that any particular attack is imminent. The phrase “advanced stages” therefore represents the intelligence community’s characterization of the maturity of some alleged plots rather than confirmation that an attack will occur. Nonetheless, the unusually direct language of the warning demonstrates the seriousness with which Washington is treating the threat.

The staffing reductions are being influenced by more than one security concern. U.S. officials say the threat from Iran-aligned Houthi attacks and separate Iranian plots targeting American officials are both shaping decisions about embassy personnel. Some American missions have been placed under Restricted Operations Status, a mechanism that allows the State Department greater flexibility to reduce staffing, restrict movements or adjust operations without always announcing a formal change in mission status publicly.

Saudi Arabia has become one of the most immediate areas of concern after an escalation in Houthi missile and drone attacks. The Iran-aligned Yemeni movement has targeted civilian airports, oil infrastructure and other strategic locations, creating serious travel disruptions and civilian casualties. The U.S. Embassy in Riyadh issued a security alert warning Americans about the possibility of further attacks and urged heightened vigilance.

King Fahd International Airport near Dammam was among the facilities struck during the latest escalation. Saudi authorities reported deaths and injuries from attacks in the eastern part of the kingdom, while another drone targeted facilities associated with Saudi Aramco. Saudi Arabia has responded by intercepting missiles and drones and carrying out strikes against Houthi military positions.

Riyadh’s King Khalid International Airport has also been affected. The airport partially reopened on Sunday after operations had been disrupted following a Houthi-claimed attack earlier in October that killed 13 people. Houthi military spokesperson Yahya Saree subsequently warned airlines and travelers that the airport remained a target, even as Saudi authorities resumed limited domestic and international services.

Those developments explain why Washington’s immediate public departure order focused on Saudi Arabia. The State Department says Iran-supported Houthis have increasingly attacked civilian airports and other critical infrastructure, resulting in casualties and severe travel disruption. U.S. diplomats and government employees working in the kingdom could therefore face danger even if they are not individually targeted.

At the same time, American intelligence officials are worried about direct Iranian operations aimed specifically at U.S. citizens and officials. The October 23 memo suggests that Washington believes the threat has moved beyond general rhetoric or contingency planning and that operational preparation may be taking place in several locations.

Iran has not publicly accepted the U.S. characterization that it is conducting advanced assassination or terrorist plots against American citizens. Tehran has repeatedly argued throughout the conflict that its military and allied operations are responses to attacks carried out by the United States and Israel, while U.S. officials accuse Iran and Iran-aligned groups of deliberately threatening American personnel, military installations and diplomatic facilities.

The latest intelligence alert comes against the background of a regional conflict that began with the U.S.-Israeli offensive against Iran in late February and is now approaching its ninth month. Fighting has involved attacks on Iranian territory, Iranian retaliation against U.S. and allied interests, disruptions to shipping, missile and drone strikes across the Gulf and an expansion of Houthi activity from Yemen.

American diplomatic facilities have already been targeted during the conflict. Reuters reported that the U.S. Embassy compound in Riyadh and a CIA station located there came under drone attack in early March as Iran launched strikes against American-linked facilities across the region. Washington withdrew or reduced diplomatic personnel from several Middle Eastern missions during that earlier phase of the war before beginning to return some employees later in the year as conditions temporarily improved.

By August, the United States had started restaffing some embassies and diplomatic posts, including missions in Saudi Arabia, Israel, Lebanon and Iraq. Some posts were expected to operate at no more than 85% of their authorized staffing during the initial return. The latest security measures therefore represent a reversal of part of that normalization and illustrate how quickly the regional risk assessment has deteriorated again.

The wider threat has prompted the State Department to update travel advisories across more than a dozen Middle Eastern and Gulf countries. Saudi Arabia remains at Level 3, meaning Americans are advised to reconsider travel, with the State Department specifically citing the threat of drone and missile attacks against American interests by Iran and Iran-supported Houthis, armed conflict and terrorism.

Qatar’s advisory was also updated on October 23 and remains at Level 3 because of armed-conflict risks. The State Department warned that additional staffing adjustments could be imposed on U.S. personnel there as the security environment evolves. Jordan’s advisory similarly notes increased concern over potential Houthi attacks and Iranian efforts to target U.S. officials in the region.

Iran itself remains under the highest Level 4 “Do Not Travel” warning. The State Department says U.S. citizens should leave immediately, citing terrorism, kidnapping, arbitrary detention, civil unrest and the risk of wrongful imprisonment. The United States has no embassy in Iran, making emergency consular assistance particularly difficult.

It is important, however, to distinguish these travel warnings from ordered evacuations. Updating a country to “Reconsider Travel” does not mean that an American embassy has closed or that all diplomatic personnel have been evacuated. Likewise, internal staffing changes under Restricted Operations Status may occur without a full embassy shutdown.

Saudi Arabia is currently the clearest publicly confirmed example of an October ordered departure. Non-emergency U.S. government employees and their families were instructed to leave, while Washington retained essential personnel to maintain diplomatic operations. U.S. officials separately said that family members at other Gulf missions would also be moved, but official public details remain incomplete.

The possibility of changes at American military bases has generated additional reporting, but the currently verified intelligence warning should not be interpreted as confirmation that Washington has ordered a wholesale evacuation of U.S. forces from the Middle East. The United States maintains tens of thousands of military personnel across bases and facilities in Qatar, Bahrain, Kuwait, the United Arab Emirates, Saudi Arabia, Jordan and Iraq, and military force-protection measures can include dispersal, relocation or temporary movement without constituting a regional withdrawal.

Those military facilities have long been viewed as potential targets in any direct confrontation with Iran. Al Udeid Air Base in Qatar hosts major U.S. air operations, Bahrain hosts the U.S. Navy’s Fifth Fleet, Kuwait supports significant American logistics operations, and additional forces operate from bases in Jordan, Iraq and elsewhere.

During earlier phases of the 2026 conflict, the United States moved personnel from exposed bases and reduced diplomatic staffing as Iranian retaliation intensified. Some American facilities were attacked, and military commanders adjusted aircraft, ships and personnel to make them more difficult to target. Similar precautionary measures could be used again if intelligence indicates a rising threat.

The present warning therefore matters because it suggests Washington is preparing not only for conventional missile and drone attacks but for potentially more targeted operations against individuals. Such plots could involve Iranian state personnel, intelligence operatives or aligned groups, although the public intelligence memo does not specify who U.S. agencies believe would carry them out.

American officials have long accused Tehran of plotting against current and former U.S. officials in retaliation for previous American military actions. Iran has denied some of those accusations while openly promising consequences for actions it considers attacks on Iranian sovereignty. That history gives U.S. security agencies additional reason to treat new intelligence seriously.

The deterioration in security also has major consequences for ordinary American citizens living or working in the region. U.S. embassies are advising citizens to monitor security alerts, maintain emergency plans, follow local authorities and prepare for airspace closures or flight disruptions. Missile and drone attacks can close airports with little warning, making commercial evacuation difficult once fighting escalates.

The experience earlier in the year demonstrated that problem. When hostilities intensified in March, flight cancellations and airspace restrictions left Americans and other foreign nationals stranded in several countries. Washington eventually facilitated charter flights from parts of the Middle East to assist citizens trying to leave.

Saudi Arabia’s aviation network has again been severely disrupted by the renewed Houthi campaign. Even when airports reopen, airlines may reduce schedules because of insurance concerns, crew safety or the possibility of additional missile strikes. The State Department has therefore emphasized that travelers should not assume commercial transportation will remain continuously available during a crisis.

The impact extends well beyond diplomacy. Saudi Aramco instructed personnel at its headquarters in Dhahran to evacuate and work remotely amid the worsening security situation, according to Reuters. The company’s facilities have been threatened during the latest Houthi attacks, demonstrating how the conflict is increasingly affecting some of the world’s most important energy infrastructure.

Oil markets have reacted accordingly. Brent crude reached its highest settlement in nearly six months on October 23, climbing above $116 per barrel as investors assessed the possibility of further disruption to Saudi production, shipping routes and Gulf energy infrastructure. West Texas Intermediate also rose sharply.

The risk to the Strait of Hormuz and Bab el-Mandeb adds another layer of global concern. These waterways are critical to international oil, liquefied natural gas and commercial shipping. Intensified Iranian or Houthi military activity around either route could affect global fuel prices and supply chains far beyond the Middle East.

The International Monetary Fund has already warned that the regional war is imposing a major economic cost. Its latest forecasts indicate that output across the Middle East, North Africa and Pakistan could contract in 2026 because of disruptions to energy production, shipping, tourism, investment and trade. Gulf economies that ordinarily benefit from large energy exports are among those facing substantial pressure from the conflict.

This economic impact increases the stakes of any further escalation between Washington and Tehran. Renewed large-scale American strikes against Iran could trigger additional Iranian retaliation against bases, embassies, shipping or U.S.-linked interests, while intensified attacks by Iranian-aligned groups could lead to new military responses from the United States and its regional partners.

Reuters previously reported that Iran was preparing a more forceful response if Washington resumed major attacks on Iranian territory. That assessment has become particularly relevant as U.S. intelligence agencies warn that Iranian planning against Americans is becoming more advanced.

The Biden-era and Trump-era history of U.S.-Iran tensions has repeatedly demonstrated that escalation can occur through indirect channels as well as direct state-to-state strikes. Militias, proxy forces, covert operations and attacks on commercial shipping can create significant pressure while allowing each side some ambiguity about the level of direct state involvement.

The Houthis remain one of the most powerful examples of that dynamic. They are politically and militarily aligned with Iran but operate as an independent Yemeni movement with their own leadership and strategic objectives. Washington describes them as Iran-supported, but that relationship does not mean every Houthi action is directly ordered by Tehran.

That distinction matters in assessing the Saudi attacks. The United States is treating Houthi strikes and Iranian plotting as related elements of the regional security environment, but they are not necessarily the same operational threat. The diplomatic evacuation from Saudi Arabia was publicly justified primarily by the surge in Houthi attacks, while the intelligence memo separately identifies Iranian lethal plotting against Americans.

The two threats intersect because both arise from a broader regional confrontation involving Iran and the United States. American officials therefore have to prepare for simultaneous risks ranging from ballistic missiles and drones to covert attacks against specific individuals.

Saudi Arabia also faces a difficult strategic position. The kingdom has sought to protect its territory and vital oil infrastructure while avoiding an uncontrolled escalation that could make Saudi cities and economic facilities permanent targets. The renewed Houthi attacks have undermined years of efforts to reduce cross-border violence from Yemen.

The partial reopening of Riyadh airport on October 25 illustrates that tension. Saudi authorities are trying to restore normal commercial activity even as Houthi leaders publicly insist the facility remains unsafe. The result is an environment in which airlines, businesses and foreign governments must make their own security calculations on top of official Saudi decisions.

For Washington, the departure of non-emergency personnel is intended to reduce the number of Americans exposed if the situation worsens. Ordered departure is a precautionary measure, not evidence that the U.S. government has determined an attack on the embassy itself is inevitable.

The same caution applies to the intelligence memo. The warning is serious, but intelligence assessments can change as new information emerges, plots are disrupted or adversaries alter their plans. U.S. officials have not publicly provided the evidence underlying the assessment, meaning independent verification of the alleged Iranian plots is not currently possible.

What can be established is that the United States has taken concrete protective measures in response. Staffing has been reduced in Saudi Arabia, diplomats and families are being moved, travel warnings have been strengthened and embassy operations across the region are being reviewed.

Those decisions suggest Washington considers the threat environment materially worse than it was only weeks ago. The fact that some missions had only recently begun returning to more normal staffing levels makes the reversal particularly notable.

Diplomatic evacuations can also affect the ability of embassies to assist ordinary citizens. When non-essential personnel and family members leave, essential consular and security functions generally continue, but routine services may become slower or more limited. Americans in the region are therefore being urged to make independent departure plans rather than relying on the assumption that the U.S. government will always be able to organize an evacuation.

The current situation remains fluid. No publicly announced decision has been made to close every U.S. embassy in the Gulf, and there is no verified order for a complete withdrawal of American military forces from the region. Reporting that describes Washington as evacuating the entire Middle East would therefore go beyond the evidence available.

Instead, the picture is one of selective but increasingly serious precautionary measures: a confirmed ordered departure from Saudi missions, planned family-member withdrawals elsewhere, elevated travel advisories, restricted diplomatic operations and heightened protection for U.S. personnel.

Those precautions are unfolding while the regional conflict itself shows signs of widening again. Houthi missile and drone attacks have intensified, Saudi air defenses are intercepting incoming weapons, oil facilities remain vulnerable and shipping risks are rising.

If Iran were to activate plots against American officials or citizens, Washington could interpret such an attack as a major escalation requiring retaliation. Likewise, a successful strike on a U.S. embassy or military facility could quickly expand the conflict.

For that reason, diplomatic staffing decisions are not merely administrative changes. They are indicators of how the U.S. government assesses danger and how seriously officials believe the possibility of additional attacks should be treated.

The coming days will be important in determining whether the measures remain precautionary or expand further. Additional embassy staffing reductions, military force-protection movements, airport closures or new Houthi and Iranian-linked attacks would indicate that the region is moving toward another period of acute escalation.

Conversely, successful interception of threats, renewed diplomatic contacts or a reduction in attacks could allow Washington to stabilize operations without a broader evacuation.

For now, the central facts are clear. American intelligence officials say Iran has substantially increased efforts to target U.S. personnel and that some lethal plots have reached advanced stages. The State Department has ordered non-emergency personnel and families to leave its missions in Saudi Arabia, officials say family members will be withdrawn from additional Gulf posts, and travel advisories across much of the region have been strengthened.

The measures do not prove that an Iranian attack is imminent, and the United States has not publicly disclosed the intelligence behind its assessment. They do, however, demonstrate that Washington sees the combination of Iranian plotting, Houthi attacks and wider regional warfare as serious enough to reduce the number of Americans exposed at diplomatic posts while keeping military and diplomatic contingency plans under constant review.

With Saudi airports and energy installations already under attack and American intelligence warning of targeted threats against U.S. citizens, the Middle East has entered another period in which a single successful strike could dramatically widen a conflict that is already approaching its ninth month.
