British Air Force Typhoon fighter aircraft have conducted a mission with French warplanes in a joint strike on an hidden munitions depot in Syrian territory used by the Daesh militant organization, according to the UK's MoD.
The location, located using intelligence, was assessed as containing munitions and bombs, the announcement noted, and was located in hills just to the north of Palmyra in Syria's central region.
"Our fighter planes employed Paveway IV guided bombs to hit a number of approach shafts down to the facility... early reports suggest the objective was successfully hit," the MoD said.
There was no indication of any civilian casualties in the strike late on Saturday and each participating jet made a safe return, the MoD added.
The Typhoon fighters were supported by a Voyager refuelling tanker.
The Islamic State group - referred to as the so-called Islamic State - established extremist governance over parts of both Syria and Iraq until 2019.
"This strike shows our UK leadership, and resolve to operate in unison with allied nations, to eliminate any revival of the terrorist group and their violent and radical beliefs in the area," the British Defence Secretary the Defence Secretary remarked.
British military aircraft have conducted patrols over Syrian airspace to "forestall any attempted comeback" of Islamic State subsequent to its routing at the Baghuz confrontation in 2019, the ministry said.
"I extend gratitude to every member of our armed forces who took part in this operation for their skill and their valour," Healey added. "They were part of thousands of British troops stationed over the festive period. This mission, to take out militants who threaten our way of life, demonstrates how our armed forces are ready to step up, all year round, protecting the UK within its borders and powerful internationally."
Last December, the United States armed forces executed what it called a "massive strike" against Islamic State objectives in the country, subsequent to an ambush killed two American soldiers and a civilian linguist in Palmyra.
The U.N. reports Daesh still boasts an estimated 5,000 to 7,000 combatants in Syria and Iraq.
