British Air Force Typhoon jets have operated alongside French aircraft in a joint strike on an hidden munitions depot in Syrian territory operated by the Daesh militant organization, as stated by the UK's MoD.
The site, identified by reconnaissance, was believed to be containing munitions and bombs, the statement said, and was positioned in mountains just above Palmyra in the heart of Syria.
"Our fighter planes employed laser-guided Paveway IV weapons to hit a several access tunnels down to the depot... early reports are that the objective was successfully hit," officials stated.
There was no sign of any civilian casualties in the operation late on Saturday and all the aircraft made a safe return, the defence officials confirmed.
The British jets were backed up by a Voyager refuelling tanker.
The Islamic State group - referred to as ISIS - imposed extremist governance over parts of Iraq and Syria prior to its 2019 collapse.
"This action underscores our UK leadership, and determination to operate in unison with allied nations, to stamp out any re-emergence of IS and their harmful and extremist ideologies in the area," the British Defence Secretary the Defence Secretary said.
UK warplanes have performed patrols over Syria to "prevent any efforts to regroup" of the group subsequent to its defeat at the Baghuz confrontation in 2019, the authorities noted.
"I must thank all the members of the UK armed forces participating in this strike for their skill and their valour," Healey commented. "They were among numerous British personnel on duty over Christmas and New Year. This mission, to remove dangerous terrorists who endanger our safety, demonstrates how our armed forces are ready to step up, continuously, protecting the UK at home and strong abroad."
Last December, the US military executed what it described as a "massive strike" on IS targets in Syria, following an assault claimed the lives of two American soldiers and a civilian linguist in the Palmyra area.
The U.N. estimates IS still maintains an estimated 5,000 to 7,000 militants in Syria and Iraq.
