British Air Force Typhoon FGR4s have conducted a mission with France's air force in a joint strike against an hidden munitions depot in Syria operated by the Daesh militant organization, according to the UK's MoD.
The site, identified by reconnaissance, was thought to be containing munitions and bombs, the announcement noted, and was located in mountains just to the north of the ancient city of Palmyra in central Syria.
"The RAF jets used laser-guided Paveway IV weapons to target a series of entry passages down to the facility... preliminary assessments are that the objective was successfully hit," the MoD said.
There was no evidence of any civilian impact in the strike late on Saturday and each participating jet made a safe return, the ministry further stated.
The Typhoon fighters were supported by a Voyager tanker plane.
The Islamic State group - referred to as the so-called Islamic State - imposed militant control over significant areas in Iraq and Syria until 2019.
"This action shows our UK leadership, and resolve to stand shoulder to shoulder with allied nations, to eliminate any re-emergence of the terrorist group and their violent and radical beliefs in the region," UK Defence Secretary John Healey remarked.
UK warplanes have conducted overwatch operations over Syria to "prevent any efforts to regroup" of IS after its military defeat at the battle of Baghuz in 2019, the MoD reported.
"I extend gratitude to the personnel of British forces who took part in this operation for their skill and their valour," the Defence Secretary added. "Including them were thousands of British personnel on duty over the holidays. This operation, to eliminate dangerous terrorists who pose a risk to our security, shows how our armed forces are prepared to act, throughout the year, protecting the UK within its borders and strong abroad."
During December, the US military executed what it called a "major assault" on Islamic State objectives in the country, following an assault resulted in the deaths of two US troops and a local interpreter in the Palmyra area.
The U.N. reports Islamic State still has roughly 5-7 thousand combatants in both countries.
