Joint UK-French Aerial Assault Strikes IS Munitions Store in the Syrian region

British Air Force Typhoon jets have joined forces with France's air force in a combined operation on an subterranean weapons facility in Syria used by the IS group, as stated by the UK's MoD.

The site, located using surveillance, was assessed as containing munitions and bombs, the statement said, and was situated in hills just north of the ancient city of Palmyra in central Syria.

"The RAF jets used laser-guided Paveway IV weapons to strike a number of entry passages leading to the depot... preliminary assessments suggest the target was engaged successfully," officials stated.

There was no sign of any civilian casualties in the operation on Saturday evening and every plane involved returned to base without incident, the ministry further stated.

The Typhoon FGR4s were assisted by a Voyager tanker plane.

Daesh - also known as ISIS - enforced jihadist rule over large swathes of both Syria and Iraq until 2019.

"This strike shows the UK's leading role, and resolve to operate in unison with our partners, to eliminate any re-emergence of Daesh and their harmful and extremist ideologies in the area," Britain's Defence Chief the Defence Secretary remarked.

UK warplanes have performed surveillance missions over Syrian airspace to "forestall any efforts to regroup" of Islamic State after its defeat at the battle of Baghuz in 2019, the ministry said.

"I want to thank every member of the UK armed forces who took part in this mission for their skill and their bravery," Healey added. "Including them were a great many UK service members on duty over the festive period. This action, to eliminate dangerous terrorists who endanger our safety, demonstrates how British military are prepared to act, continuously, ensuring Britain's security within its borders and influential overseas."

Last December, the American forces carried out what it described as a "massive strike" targeting Daesh sites in Syria, after an ambush killed two US troops and a civilian linguist in Palmyra.

The U.N. estimates Islamic State still boasts an estimated 5,000 to 7,000 fighters in both countries.
