Royal Air Force Typhoon FGR4s have joined forces with French aircraft in a combined operation on an subterranean weapons facility in Syria used by the IS group, per a report from the UK's MoD.
The facility, pinpointed through surveillance, was thought to be housing weapons and explosive materials, the release indicated, and was situated in mountainous terrain just north of the historic site of Palmyra in Syria's central region.
"Our aircraft employed Paveway IV guided bombs to strike a several approach shafts down to the facility... preliminary assessments are that the objective was successfully hit," the ministry announced.
There was no indication of any civilian impact in the operation late on Saturday and each participating jet made a safe return, the ministry further stated.
The Typhoon FGR4s were supported by a Voyager aerial refuelling aircraft.
Daesh - referred to as ISIS - established extremist governance over parts of Iraq and Syria before its territorial defeat in 2019.
"This operation demonstrates British leadership, and commitment to stand shoulder to shoulder with our allies, to eliminate any re-emergence of the terrorist group and their dangerous and violent ideologies in the Middle East," Britain's Defence Chief the minister remarked.
British military aircraft have conducted overwatch operations over Syrian airspace to "deter any efforts to regroup" of Islamic State after its defeat at the climactic battle in Baghuz in 2019, the authorities noted.
"I must thank all the members of British forces who took part in this mission for their expertise and their valour," Healey said. "They were part of a great many British troops deployed over Christmas and New Year. This action, to remove militants who endanger our security, demonstrates how UK forces are prepared to act, throughout the year, keeping Britain secure at home and strong abroad."
During December, the United States armed forces conducted what it described as a "large-scale strike" targeting Daesh sites in Syria, following an attack killed two American soldiers and a civilian linguist in the Palmyra area.
The U.N. reports Islamic State still boasts between 5,000 and 7,000 fighters in both countries.
