RAF Typhoon fighter aircraft have joined forces with French warplanes in a combined operation against an underground arms cache in Syria employed by the IS group, as stated by the UK Ministry of Defence.
The facility, identified by intelligence, was believed to be storing arms and explosives, the release indicated, and was located in mountains just to the north of the historic site of Palmyra in Syria's central region.
"Our aircraft employed laser-guided Paveway IV weapons to strike a several access tunnels providing entry to the depot... initial indications suggest the strike was effective," the MoD said.
There was no evidence of any civilian casualties in the attack conducted Saturday night and each participating jet returned to base without incident, the ministry further stated.
The Typhoon FGR4s were supported by a Voyager aerial refuelling aircraft.
Daesh - alternatively referred to as ISIS - established extremist governance over significant areas in Iraq and Syria until 2019.
"This operation shows our UK leadership, and resolve 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 minister remarked.
RAF aircraft have carried out surveillance missions over Syria to "prevent any attempted comeback" of the group subsequent to its military defeat at the Baghuz confrontation in 2019, the authorities noted.
"I extend gratitude to all the members of the UK armed forces participating in this mission for their skill and their courage," he commented. "Including them were thousands of British troops on duty over the festive period. This action, to remove militants who endanger our security, demonstrates how UK forces are always on standby, throughout the year, keeping Britain secure at home and strong abroad."
Last December, the American forces executed what it termed a "massive strike" targeting Islamic State objectives in the country, after an attack killed two US servicemembers and a civilian interpreter in Palmyra.
The UN says Islamic State still has an estimated 5,000 to 7,000 fighters in Iraq and Syria.
