British Air Force Typhoon FGR4s have conducted a mission with French warplanes in a joint strike against an underground arms cache in Syrian territory operated by the Daesh militant organization, as stated by the UK Ministry of Defence.
The site, pinpointed through intelligence, was assessed as storing arms and explosives, the release indicated, and was situated in mountains just to the north of the historic site of Palmyra in the heart of Syria.
"The RAF jets used precision-guided Paveway IV munitions to strike a several approach shafts providing entry to the depot... preliminary assessments indicate the strike was effective," the MoD said.
There was no sign of any harm to civilians in the operation on Saturday evening and all the aircraft made a safe return, the ministry further stated.
The Typhoon FGR4s were supported by a Voyager refuelling tanker.
The Islamic State group - referred to as the so-called Islamic State - enforced jihadist rule over parts of Iraq and Syria prior to its 2019 collapse.
"This strike underscores our UK leadership, and resolve to stand shoulder to shoulder with our allies, to eliminate any re-emergence of IS and their violent and radical beliefs in the Middle East," the British Defence Secretary the Defence Secretary said.
UK warplanes have performed surveillance missions over Syria to "forestall any efforts to regroup" of IS following its defeat at the Baghuz confrontation in the year 2019, the ministry said.
"I extend gratitude to every member of the UK armed forces participating in this operation for their skill and their valour," Healey said. "They were among a great many UK service members stationed over Christmas and New Year. This operation, to eliminate terrorist threats who threaten our way of life, shows how UK forces are prepared to act, all year round, protecting the UK domestically and powerful internationally."
Last December, the United States armed forces executed what it termed a "large-scale strike" on IS targets in Syria, subsequent to an ambush killed two American soldiers and a civilian interpreter in the Palmyra area.
The United Nations says Islamic State still boasts roughly 5-7 thousand militants in both countries.
