RAF Typhoon jets have conducted a mission with France's air force in a coordinated attack on an underground arms cache in Syria employed by the IS group, as stated by the UK's MoD.
The location, located using reconnaissance, was believed to be containing munitions and bombs, the release indicated, and was situated in mountains just above Palmyra in central Syria.
"Our fighter planes employed laser-guided Paveway IV weapons to hit a series of access tunnels leading to the depot... preliminary assessments are that the objective was successfully hit," officials stated.
There was no sign of any civilian impact in the operation late on Saturday and each participating jet returned safely, the ministry further stated.
The British jets were assisted by a Voyager refuelling tanker.
Daesh - alternatively referred to as the so-called Islamic State - established extremist governance over large swathes of Syria and Iraq until 2019.
"This operation shows British leadership, and determination to stand shoulder to shoulder with our allies, to eliminate any revival of the terrorist group and their violent and radical beliefs in the region," the British Defence Secretary the minister stated.
UK warplanes have carried out overwatch operations over Syrian airspace to "prevent any efforts to regroup" of the group subsequent to its defeat at the battle of Baghuz in the year 2019, the authorities noted.
"I want to thank every member of the UK armed forces involved in this mission for their skill and their valour," Healey said. "Including them were thousands of UK service members on duty over the holidays. This action, to remove dangerous terrorists who endanger our safety, demonstrates how British military are always on standby, throughout the year, keeping Britain secure domestically and powerful internationally."
Last December, the United States armed forces conducted what it described as a "massive strike" on Islamic State objectives in Syria, subsequent to an assault resulted in the deaths of two US troops and a civilian linguist in Palmyra.
The United Nations says Daesh still maintains an estimated 5,000 to 7,000 combatants in both countries.
