Royal Air Force Typhoon jets have joined forces with France's air force in a combined operation against an hidden munitions depot in Syria used by the Islamic State group (IS), per a report from the British defence ministry.
The site, located using reconnaissance, was thought to be containing munitions and bombs, the statement said, and was situated in hills just north of the historic site of Palmyra in the heart of Syria.
"Our aircraft used laser-guided Paveway IV weapons to hit a several entry passages down to the facility... early reports suggest the objective was successfully hit," the MoD said.
There was no sign of any civilian impact in the attack conducted Saturday night and each participating jet made a safe return, the MoD added.
The British jets were backed up by a Voyager aerial refuelling aircraft.
Daesh - referred to as ISIS - imposed militant control over parts of both Syria and Iraq prior to its 2019 collapse.
"This strike demonstrates British leadership, and resolve to operate in unison with allied nations, to eliminate any resurgence of the terrorist group and their dangerous and violent ideologies in the region," UK Defence Secretary the minister stated.
RAF aircraft have conducted patrols over Syrian airspace to "forestall any attempted comeback" of the group after its military defeat at the battle of Baghuz in 2019, the MoD reported.
"I must thank every member of our armed forces involved in this strike for their expertise and their valour," the Defence Secretary added. "Including them were numerous British troops deployed over the festive period. This action, to eliminate dangerous terrorists who endanger our way of life, shows how UK forces are ready to step up, all year round, ensuring Britain's security within its borders and influential overseas."
Last December, the United States armed forces executed what it described as a "large-scale strike" against IS targets in the country, subsequent to an ambush killed two US servicemembers and a civilian interpreter in Palmyra.
The U.N. says Islamic State still has roughly 5-7 thousand fighters in both countries.
