Royal Air Force Typhoon FGR4s have conducted a mission with French aircraft in a coordinated attack against an hidden munitions depot in Syria operated by the Daesh militant organization, as stated by the British defence ministry.
The site, located using surveillance, was assessed as housing weapons and explosive materials, the announcement noted, and was positioned in mountains just north of Palmyra in Syria's central region.
"Our fighter planes employed laser-guided Paveway IV weapons to target a several entry passages down to the depot... preliminary assessments are that the objective was successfully hit," the MoD said.
There was no sign of any civilian casualties in the strike late on Saturday and all the aircraft returned safely, the MoD added.
The Typhoon fighters were assisted by a Voyager tanker plane.
The Islamic State group - referred to as ISIS - established jihadist rule over large swathes of both Syria and Iraq prior to its 2019 collapse.
"This operation underscores British leadership, and resolve to work closely with our allies, to stamp out any re-emergence of IS and their dangerous and violent ideologies in the region," the British Defence Secretary the Defence Secretary said.
UK warplanes have carried out surveillance missions over Syria to "prevent any efforts to regroup" of Islamic State following its routing at the Baghuz confrontation in 2019, the ministry said.
"I must thank all the members of the UK armed forces participating in this operation for their professionalism and their courage," he said. "They were among numerous UK service members on duty over the festive period. This mission, to take out militants who endanger our safety, shows how British military are prepared to act, continuously, keeping Britain secure within its borders and powerful internationally."
Last December, the US military executed what it called a "large-scale strike" targeting IS targets in Syria, after an ambush killed two American soldiers and a civilian linguist in the Palmyra area.
The United Nations reports Islamic State still maintains an estimated 5,000 to 7,000 militants in Iraq and Syria.
