British Air Force Typhoon fighter aircraft have joined forces with France's air force in a combined operation on an subterranean weapons facility in Syrian territory used by the Daesh militant organization, according to the British defence ministry.
The facility, identified by reconnaissance, was assessed as storing arms and explosives, the release indicated, and was situated in mountains just to the north of the historic site of Palmyra in central Syria.
"The RAF jets employed Paveway IV guided bombs to hit a number of access tunnels leading to the facility... initial indications indicate the target was engaged successfully," the MoD said.
There was no indication of any harm to civilians in the strike on Saturday evening and all the aircraft returned to base without incident, the ministry further stated.
The Typhoon fighters were backed up by a Voyager tanker plane.
The Islamic State group - alternatively referred to as ISIS - imposed extremist governance over large swathes of both Syria and Iraq before its territorial defeat in 2019.
"This strike underscores the UK's leading role, and commitment to work closely with our allies, to eliminate any re-emergence of Daesh and their violent and radical beliefs in the area," UK Defence Secretary the minister remarked.
UK warplanes have carried out overwatch operations over Syria to "deter any efforts to regroup" of Islamic State subsequent to its routing at the Baghuz confrontation in 2019, the ministry said.
"I must thank all the members of our armed forces who took part in this strike for their professionalism and their courage," the Defence Secretary commented. "Including them were numerous UK service members on duty over the festive period. This action, to remove militants who endanger our way of life, demonstrates how UK forces are ready to step up, throughout the year, keeping Britain secure domestically and strong abroad."
Last December, the US military carried out what it described as a "major assault" against Islamic State objectives in the country, after an assault resulted in the deaths of two US servicemembers and a civilian linguist in Palmyra.
The United Nations says Islamic State still has roughly 5-7 thousand combatants in Iraq and Syria.
