British Air Force Typhoon jets have joined forces with France's air force in a coordinated attack against an underground arms cache in Syria employed by the IS group, as stated by the British defence ministry.
The facility, identified by surveillance, was believed to be containing munitions and bombs, the statement said, and was located in mountainous terrain just to the north of the ancient city of Palmyra in the heart of Syria.
"Our fighter planes used laser-guided Paveway IV weapons to target a number of approach shafts leading to the depot... initial indications suggest the objective was successfully hit," the ministry announced.
There was no indication of any civilian casualties in the operation conducted Saturday night and all the aircraft returned safely, the ministry further stated.
The Typhoon fighters were backed up by a Voyager aerial refuelling aircraft.
The Islamic State group - referred to as Daesh - established extremist governance over large swathes of Syria and Iraq before its territorial defeat in 2019.
"This operation underscores British leadership, and determination to work closely with allied nations, to eradicate any resurgence of the terrorist group and their violent and radical beliefs in the region," the British Defence Secretary the minister remarked.
UK warplanes have conducted overwatch operations over Syria to "forestall any attempted comeback" of Islamic State subsequent to its routing at the climactic battle in Baghuz in 2019, the MoD reported.
"I must thank all the members of our armed forces involved in this operation for their expertise and their courage," Healey said. "They were part of a great many UK service members deployed over Christmas and New Year. This action, to remove dangerous terrorists who threaten our security, shows how our armed forces are prepared to act, all year round, keeping Britain secure at home and strong abroad."
During December, the American forces executed what it termed a "large-scale strike" targeting Islamic State objectives in the country, subsequent to an ambush resulted in the deaths of two American soldiers and a civilian linguist in Palmyra.
The United Nations estimates Daesh still has an estimated 5,000 to 7,000 militants in both countries.
