Joint British-French Aerial Assault Strikes Islamic State Weapons Depot in the Syrian region

British Air Force Typhoon FGR4s have operated alongside France's air force in a joint strike against an underground arms cache in Syrian territory employed by the IS group, per a report from the UK's MoD.

The facility, pinpointed through reconnaissance, was thought to be storing arms and explosives, the announcement noted, and was positioned in mountains just to the north of the historic site of Palmyra in central Syria.

"The RAF jets used precision-guided Paveway IV munitions to hit a number of approach shafts providing entry to the site... early reports are that the objective was successfully hit," the MoD said.

There was no evidence of any civilian casualties in the operation on Saturday evening and each participating jet returned to base without incident, the defence officials confirmed.

The Typhoon FGR4s were backed up by a Voyager refuelling tanker.

Daesh - referred to as Daesh - imposed extremist governance over parts of Syria and Iraq prior to its 2019 collapse.

"This strike underscores British leadership, and resolve to operate in unison with allied nations, to stamp out any revival of the terrorist group and their harmful and extremist ideologies in the area," Britain's Defence Chief the minister stated.

RAF aircraft have conducted patrols over Syria to "forestall any efforts to regroup" of IS following its routing at the Baghuz confrontation in 2019, the ministry said.

"I want to thank every member of the UK armed forces who took part in this operation for their skill and their bravery," Healey added. "They were among thousands of British troops deployed over the festive period. This operation, to take out militants who endanger our way of life, highlights how our armed forces are always on standby, continuously, keeping Britain secure at home and strong abroad."

Last December, the US military executed what it called a "large-scale strike" targeting IS targets in Syria, after an assault claimed the lives of two US troops and a civilian linguist in Palmyra.

The U.N. says Islamic State still has roughly 5-7 thousand militants in Iraq and Syria.
