Royal Air Force Typhoon fighter aircraft have operated alongside French aircraft in a joint strike against an hidden munitions depot in Syria operated by the IS group, as stated by the UK's MoD.
The location, located using reconnaissance, was thought to be containing munitions and bombs, the announcement noted, and was located in mountainous terrain just above the historic site of Palmyra in the heart of Syria.
"The RAF jets used Paveway IV guided bombs to target a number of entry passages leading to the facility... preliminary assessments suggest the strike was effective," the ministry announced.
There was no evidence of any civilian impact in the strike conducted Saturday night and every plane involved made a safe return, the ministry further stated.
The British jets were assisted by a Voyager refuelling tanker.
The Islamic State group - also known as the so-called Islamic State - imposed militant control over parts of both Syria and Iraq until 2019.
"This strike demonstrates our UK leadership, and resolve to operate in unison with allied nations, to eliminate any revival of IS and their violent and radical beliefs in the area," the British Defence Secretary John Healey remarked.
RAF aircraft have performed surveillance missions over Syrian airspace to "deter any attempted comeback" of the group subsequent to its military defeat at the battle of Baghuz in 2019, the authorities noted.
"I must thank all the members of the UK armed forces participating in this strike for their expertise and their courage," Healey said. "Including them were a great many UK service members on duty over the festive period. This operation, to remove terrorist threats who threaten our way of life, demonstrates how UK forces are ready to step up, continuously, ensuring Britain's security within its borders and strong abroad."
Last December, the US military conducted what it termed a "large-scale strike" against Daesh sites in Syria, following an assault killed two American soldiers and a local interpreter in the Palmyra area.
The U.N. reports Islamic State still boasts between 5,000 and 7,000 militants in Iraq and Syria.
