British Air Force Typhoon fighter aircraft 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 Ministry of Defence.
The facility, pinpointed through surveillance, was thought to be storing arms and explosives, the announcement noted, and was positioned in hills just north of Palmyra in central Syria.
"The RAF jets used laser-guided Paveway IV weapons to hit a series of access tunnels down to the depot... early reports suggest the strike was effective," the ministry announced.
There was no evidence of any civilian casualties in the operation conducted Saturday night and every plane involved returned to base without incident, the ministry further stated.
The British jets were assisted by a Voyager refuelling tanker.
Daesh - alternatively referred to as ISIS - established extremist governance over parts of both Syria and Iraq prior to its 2019 collapse.
"This operation underscores our UK leadership, and commitment to operate in unison with allied nations, to stamp out any re-emergence of the terrorist group and their violent and radical beliefs in the Middle East," UK Defence Secretary John Healey remarked.
RAF aircraft have carried out patrols over Syrian airspace to "prevent any attempted comeback" of IS following its defeat at the Baghuz confrontation in 2019, the MoD reported.
"I must thank the personnel of the UK armed forces participating in this strike for their professionalism and their courage," he added. "They were part of a great many UK service members on duty over the festive period. This action, to take out dangerous terrorists who pose a risk to our safety, demonstrates how UK forces are ready to step up, all year round, ensuring Britain's security at home and powerful internationally."
Last December, the American forces executed what it described as a "massive strike" targeting Islamic State objectives in Syria, subsequent to an ambush killed two US troops and a local interpreter in the Palmyra area.
The United Nations says Daesh still maintains between 5,000 and 7,000 combatants in Iraq and Syria.
