Royal Air Force Typhoon FGR4s have operated alongside France's air force in a combined operation on an subterranean weapons facility in Syrian territory operated by the IS group, as stated by the UK Ministry of Defence.
The site, identified by reconnaissance, was thought to be containing munitions and bombs, the statement said, and was positioned in mountainous terrain just to the north of the historic site of Palmyra in central Syria.
"Our fighter planes employed precision-guided Paveway IV munitions to target a several entry passages leading to the facility... initial indications are that the strike was effective," officials stated.
There was no indication of any civilian casualties in the strike conducted Saturday night and every plane involved returned to base without incident, the ministry further stated.
The Typhoon FGR4s were assisted by a Voyager tanker plane.
The Islamic State group - referred to as Daesh - imposed militant control over significant areas in both Syria and Iraq before its territorial defeat in 2019.
"This operation demonstrates our UK leadership, and resolve to work closely with our allies, to stamp out any resurgence of Daesh and their dangerous and violent ideologies in the area," the British Defence Secretary the minister remarked.
British military aircraft have conducted surveillance missions over Syrian airspace to "deter any attempted comeback" of the group after its military defeat at the Baghuz confrontation in 2019, the authorities noted.
"I want to thank every member of British forces who took part in this strike for their expertise and their courage," he commented. "Including them were numerous UK service members stationed over the holidays. This action, to take out terrorist threats who endanger our security, demonstrates how our armed forces are prepared to act, throughout the year, keeping Britain secure at home and strong abroad."
During December, the American forces executed what it described as a "major assault" on Daesh sites in the country, subsequent to an attack killed two American soldiers and a civilian interpreter in Palmyra.
The UN reports Islamic State still has an estimated 5,000 to 7,000 fighters in Iraq and Syria.
