Combined Anglo-French Airstrike Strikes Daesh Arms Cache in the Syrian region

British Air Force Typhoon FGR4s have conducted a mission with France's air force in a coordinated attack on an subterranean weapons facility in Syria used by the Islamic State group (IS), as stated by the British defence ministry.

The facility, pinpointed through reconnaissance, was believed to be containing munitions and bombs, the release indicated, and was positioned in mountainous terrain just above Palmyra in the heart of Syria.

"Our fighter planes employed Paveway IV guided bombs to target a series of approach shafts down to the site... early reports are that the target was engaged successfully," the ministry announced.

There was no sign of any civilian impact in the strike conducted Saturday night and each participating jet returned safely, the defence officials confirmed.

The Typhoon FGR4s were supported by a Voyager aerial refuelling aircraft.

The Islamic State group - also known as ISIS - enforced jihadist rule over significant areas in Syria and Iraq prior to its 2019 collapse.

"This action shows British leadership, and commitment to operate in unison with allied nations, to eliminate any revival of the terrorist group and their dangerous and violent ideologies in the Middle East," UK Defence Secretary the minister stated.

UK warplanes have carried out patrols over Syria to "forestall any attempted resurgence" of IS following its military defeat at the climactic battle in Baghuz in 2019, the MoD reported.

"I must thank all the members of the UK armed forces who took part in this strike for their professionalism and their courage," Healey said. "They were part of a great many British personnel deployed over the holidays. This operation, to take out militants who threaten our security, demonstrates how UK forces are ready to step up, all year round, keeping Britain secure within its borders and strong abroad."

In December, the American forces executed what it described as a "large-scale strike" against Islamic State objectives in Syria, following an assault killed two American soldiers and a civilian linguist in Palmyra.

The U.N. says Daesh still maintains an estimated 5,000 to 7,000 combatants in Iraq and Syria.
