Royal Air Force Typhoon fighter aircraft have operated alongside 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 location, pinpointed through intelligence, was assessed as housing weapons and explosive materials, the statement said, and was situated in mountains just north of the historic site of Palmyra in central Syria.
"Our aircraft utilized laser-guided Paveway IV weapons to hit a number of entry passages down to the depot... early reports indicate the strike was effective," the ministry announced.
There was no evidence of any civilian casualties in the strike on Saturday evening and every plane involved made a safe return, the MoD added.
The Typhoon fighters were backed up by a Voyager refuelling tanker.
Daesh - also known as ISIS - established jihadist rule over parts of Syria and Iraq prior to its 2019 collapse.
"This action underscores the UK's leading role, and determination to work closely with our allies, to eradicate any resurgence of IS and their dangerous and violent ideologies in the region," the British Defence Secretary the Defence Secretary said.
British military aircraft have carried out overwatch operations over Syrian airspace to "deter any efforts to regroup" of the group subsequent to its defeat at the climactic battle in Baghuz in 2019, the MoD reported.
"I must thank the personnel of British forces involved in this strike for their professionalism and their bravery," Healey commented. "They were part of numerous British personnel stationed over the holidays. This mission, to eliminate dangerous terrorists who threaten our way of life, highlights how British military are prepared to act, continuously, keeping Britain secure within its borders and strong abroad."
Last December, the United States armed forces conducted what it termed a "massive strike" against IS targets in the country, subsequent to an attack killed two US servicemembers and a civilian linguist in the Palmyra area.
The UN says Daesh still has between 5,000 and 7,000 combatants in Iraq and Syria.
