RAF Typhoon fighter aircraft have joined forces with France's air force in a combined operation targeting an underground arms cache in Syrian territory employed by the Daesh militant organization, as stated by the UK's MoD.
The location, located using surveillance, was thought to be containing munitions and bombs, the statement said, and was located in mountains just to the north of the ancient city of Palmyra in the heart of Syria.
"Our aircraft employed Paveway IV guided bombs to hit a number of entry passages leading to the facility... early reports are that the target was engaged successfully," the ministry announced.
There was no indication of any harm to civilians in the operation conducted Saturday night and all the aircraft returned to base without incident, the ministry further stated.
The British jets were supported by a Voyager refuelling tanker.
The Islamic State group - also known as the so-called Islamic State - established extremist governance over parts of Iraq and Syria prior to its 2019 collapse.
"This strike demonstrates our UK leadership, and resolve to operate in unison with allied nations, to stamp out any revival of the terrorist group and their dangerous and violent ideologies in the region," the British Defence Secretary John Healey said.
British military aircraft have conducted overwatch operations over Syria to "forestall any efforts to regroup" of the group following its military defeat at the Baghuz confrontation in 2019, the ministry said.
"I must thank the personnel of the UK armed forces involved in this strike for their professionalism and their bravery," he commented. "Including them were thousands of British personnel deployed over the festive period. This action, to eliminate dangerous terrorists who endanger our safety, shows how UK forces are ready to step up, all year round, protecting the UK at home and strong abroad."
In December, the US military conducted what it termed a "large-scale strike" targeting Islamic State objectives in the country, after an ambush killed two US servicemembers and a civilian interpreter in Palmyra.
The UN estimates Daesh still maintains roughly 5-7 thousand militants in Syria and Iraq.
