RAF Typhoon jets have joined forces with France's air force in a joint strike on an hidden munitions depot in Syrian territory employed by the IS group, per a report from the UK's MoD.
The location, identified by intelligence, was believed to be containing munitions and bombs, the release indicated, and was situated in mountainous terrain just north of the ancient city of Palmyra in Syria's central region.
"The RAF jets employed laser-guided Paveway IV weapons to hit a several approach shafts down to the facility... early reports indicate the objective was successfully hit," officials stated.
There was no evidence of any harm to civilians in the operation on Saturday evening and every plane involved made a safe return, the MoD added.
The Typhoon fighters were assisted by a Voyager refuelling tanker.
IS - also known as ISIS - imposed jihadist rule over large swathes of Syria and Iraq prior to its 2019 collapse.
"This action demonstrates the UK's leading role, and determination to work closely with allied nations, to stamp out any revival of Daesh and their dangerous and violent ideologies in the area," UK Defence Secretary the Defence Secretary remarked.
UK warplanes have conducted patrols over Syrian airspace to "prevent any efforts to regroup" of IS after its defeat at the climactic battle in Baghuz in 2019, the MoD reported.
"I want to thank the personnel of our armed forces participating in this mission for their skill and their valour," the Defence Secretary commented. "They were part of thousands of UK service members deployed over the holidays. This operation, to eliminate dangerous terrorists who threaten our safety, highlights how UK forces are ready to step up, all year round, ensuring Britain's security at home and strong abroad."
In December, the US military executed what it called a "large-scale strike" on Daesh sites in Syria, subsequent to an ambush killed two American soldiers and a civilian interpreter in Palmyra.
The U.N. reports IS still has roughly 5-7 thousand combatants in Syria and Iraq.
