RAF Typhoon FGR4s have joined forces with French aircraft in a combined operation targeting an hidden munitions depot in Syria employed by the IS group, per a report from the UK's MoD.
The facility, pinpointed through intelligence, was believed to be containing munitions and bombs, the announcement noted, and was located in mountains just above the ancient city of Palmyra in central Syria.
"Our fighter planes employed laser-guided Paveway IV weapons to target a several approach shafts down to the site... early reports indicate the objective was successfully hit," officials stated.
There was no indication of any harm to civilians in the attack late on Saturday and each participating jet made a safe return, the ministry further stated.
The British jets were supported by a Voyager tanker plane.
Daesh - also known as the so-called Islamic State - enforced militant control over large swathes of Syria and Iraq prior to its 2019 collapse.
"This operation shows British leadership, and determination to work closely with our allies, to eradicate any re-emergence of Daesh and their dangerous and violent ideologies in the region," the British Defence Secretary the Defence Secretary stated.
British military aircraft have conducted surveillance missions over Syrian airspace to "forestall any efforts to regroup" of IS after its routing at the climactic battle in Baghuz in 2019, the ministry said.
"I must thank all the members of the UK armed forces participating in this mission for their expertise and their courage," he added. "Including them were a great many British personnel stationed over the festive period. This action, to remove dangerous terrorists who endanger our safety, demonstrates how our armed forces are always on standby, throughout the year, ensuring Britain's security within its borders and strong abroad."
Last December, the United States armed forces carried out what it termed a "major assault" on Islamic State objectives in the country, subsequent to an attack claimed the lives of two US servicemembers and a civilian interpreter in Palmyra.
The U.N. says Daesh still maintains an estimated 5,000 to 7,000 combatants in Syria and Iraq.
