Yemen's Houthi movement has released video claiming its forces shot down a Saudi Arabian F15 fighter jet over Marib Governorate, in what could mark a significant escalation in renewed fighting between the Iran aligned group and Saudi Arabia.

The Houthis said the Saudi aircraft was brought down on Wednesday using a locally manufactured surface to air missile while the fighter was conducting military operations over Marib.

Saudi Arabia has not publicly confirmed the loss of the aircraft or commented on the Houthi claim. The fate of the aircraft's two crew members also remains unclear.

VIDEO SHOWS WRECKAGE OF SAUDI AIRCRAFT

Footage released by the Houthis shows what the group says was the missile engagement followed by fighters examining aircraft wreckage scattered across a desert area.

Images show a tail section carrying Saudi markings and the identification number 5539.

Defence publication Janes examined the footage and identified the wreckage as belonging to a Royal Saudi Air Force F15SA, one of the kingdom's advanced versions of the US built F15 fighter.

However, the Houthis' claim that their missile was responsible for bringing down the aircraft has not been independently established.

The crash site has been identified as being in Yemen's Marib region, where fighting has intensified as Houthi forces expand operations against Saudi backed Yemeni forces.

HOUTHIS CLAIM LOCALLY MADE MISSILE DOWNED JET

Houthi military spokesperson Yahya Saree said the aircraft was hit by a locally manufactured surface to air missile.

The group has not publicly identified the exact missile system it says was used.

Houthi forces have developed an increasingly sophisticated air defence capability during Yemen's prolonged conflict and have previously brought down drones and threatened crewed military aircraft.

The group operates a mixture of missile systems and air defence equipment while also receiving military support and technology from Iran, according to international assessments.

FIGHTING INTENSIFIES ACROSS YEMEN

The reported incident comes amid a major escalation between the Houthis and Saudi Arabia.

Houthi forces have made territorial gains in Yemen and stepped up missile and drone attacks against Saudi targets.

Saudi Arabia has responded with intensified airstrikes against Houthi controlled areas.

The fighting has also increased concerns about global energy supplies and shipping routes around the Red Sea and Bab el Mandeb, one of the world's strategically important maritime corridors.

The Houthis have seized Yemen's Red Sea coastline and have threatened Saudi linked shipping as the conflict spreads.

More than 100,000 Yemenis have also been displaced during the latest fighting, according to reporting on the escalating conflict.

SAUDI ARABIA YET TO CONFIRM LOSS

Riyadh has not officially acknowledged losing an F15 in the incident.

That distinction remains important because while available footage appears to establish that a Saudi F15 was destroyed, the circumstances surrounding how the aircraft came down have not been independently confirmed.

The status of its crew also remains unknown.

If the Houthi account of the shootdown is independently confirmed, the incident would demonstrate the growing threat posed by the group's air defence systems to advanced combat aircraft operating over Yemen.

For now, the footage provides significant evidence of a Saudi aircraft loss while the Houthi claim about exactly how it was brought down remains subject to further verification.
