RAF Typhoon FGR4s have joined forces with French warplanes in a coordinated attack targeting an subterranean weapons facility in Syria used by the Daesh militant organization, per a report from the UK Ministry of Defence.
The facility, pinpointed through intelligence, was believed to be storing arms and explosives, the statement said, and was situated in hills just above the ancient city of Palmyra in the heart of Syria.
"The RAF jets employed laser-guided Paveway IV weapons to target a series of entry passages down to the facility... early reports are that the objective was successfully hit," the ministry announced.
There was no evidence of any civilian impact in the strike on Saturday evening and each participating jet returned to base without incident, the defence officials confirmed.
The Typhoon FGR4s were supported by a Voyager refuelling tanker.
IS - also known as ISIS - enforced extremist governance over parts of both Syria and Iraq until 2019.
"This action underscores the UK's leading role, and resolve to stand shoulder to shoulder with our allies, to eliminate any re-emergence of the terrorist group and their dangerous and violent ideologies in the Middle East," Britain's Defence Chief the Defence Secretary remarked.
RAF aircraft have conducted patrols over Syrian airspace to "deter any efforts to regroup" of the group subsequent to its routing at the Baghuz confrontation in the year 2019, the authorities noted.
"I must thank every member of our armed forces participating in this mission for their professionalism and their courage," he added. "They were among numerous UK service members on duty over Christmas and New Year. This operation, to take out terrorist threats who endanger our safety, shows how our armed forces are ready to step up, continuously, keeping Britain secure domestically and powerful internationally."
In December, the US military carried out what it described as a "major assault" on Islamic State objectives in the country, following an attack killed two US troops and a civilian linguist in Palmyra.
The United Nations says IS still has roughly 5-7 thousand fighters in Syria and Iraq.
