RAF Typhoon fighter aircraft have operated alongside French warplanes in a coordinated attack targeting an hidden munitions depot in Syrian territory employed by the IS group, according to the UK's MoD.
The location, located using intelligence, was assessed as storing arms and explosives, the statement said, and was situated in mountains just north of the historic site of Palmyra in central Syria.
"Our fighter planes utilized precision-guided Paveway IV munitions to strike a several access tunnels providing entry to the depot... initial indications suggest the strike was effective," the MoD said.
There was no indication of any harm to civilians in the attack conducted Saturday night and each participating jet returned safely, the ministry further stated.
The British jets were backed up by a Voyager aerial refuelling aircraft.
The Islamic State group - referred to as the so-called Islamic State - established extremist governance over large swathes of Syria and Iraq prior to its 2019 collapse.
"This action shows British leadership, and determination to work closely with allied nations, to eliminate any resurgence of the terrorist group and their harmful and extremist ideologies in the area," UK Defence Secretary John Healey stated.
British military aircraft have performed surveillance missions over Syria to "prevent any efforts to regroup" of the group following its defeat at the battle of Baghuz in 2019, the ministry said.
"I want to thank the personnel of British forces participating in this operation for their professionalism and their valour," he commented. "They were among thousands of British personnel stationed over the festive period. This operation, to remove dangerous terrorists who endanger our security, demonstrates how UK forces are ready to step up, continuously, ensuring Britain's security domestically and powerful internationally."
During December, the US military conducted what it described as a "massive strike" against IS targets in Syria, subsequent to an ambush resulted in the deaths of two US troops and a civilian interpreter in the Palmyra area.
The U.N. reports Islamic State still maintains roughly 5-7 thousand fighters in Iraq and Syria.
