British Air Force Typhoon FGR4s have operated alongside France's air force in a joint strike on an underground arms cache in Syrian territory employed by the IS group, per a report from the UK's MoD.
The facility, located using surveillance, was thought to be storing arms and explosives, the release indicated, and was situated in hills just to the north of the ancient city of Palmyra in the heart of Syria.
"Our aircraft employed laser-guided Paveway IV weapons to hit a number of entry passages providing entry to the facility... early reports suggest the objective was successfully hit," officials stated.
There was no indication of any civilian impact in the strike late on Saturday and all the aircraft made a safe return, the ministry further stated.
The Typhoon fighters were supported by a Voyager aerial refuelling aircraft.
IS - also known as ISIS - established militant control over significant areas in Iraq and Syria prior to its 2019 collapse.
"This operation demonstrates our UK leadership, and resolve to work closely with allied nations, to eradicate any re-emergence of IS and their dangerous and violent ideologies in the area," UK Defence Secretary the Defence Secretary remarked.
RAF aircraft have performed surveillance missions over Syrian airspace to "deter any efforts to regroup" of Islamic State after its military defeat at the Baghuz confrontation in 2019, the ministry said.
"I must thank the personnel of the UK armed forces involved in this mission for their professionalism and their valour," he commented. "Including them were thousands of UK service members deployed over Christmas and New Year. This action, to take out militants who threaten our security, highlights how our armed forces are ready to step up, continuously, protecting the UK within its borders and strong abroad."
Last December, the United States armed forces conducted what it called a "major assault" targeting Islamic State objectives in the country, following an attack killed two US troops and a local interpreter in the Palmyra area.
The UN estimates Islamic State still has between 5,000 and 7,000 combatants in Syria and Iraq.
