Royal Air Force Typhoon fighter aircraft have operated alongside France's air force in a joint strike targeting an underground arms cache in Syrian territory operated by the IS group, per a report from the UK's MoD.
The facility, identified by surveillance, was thought to be containing munitions and bombs, the release indicated, and was positioned in mountains just north of the ancient city of Palmyra in central Syria.
"Our fighter planes used precision-guided Paveway IV munitions to hit a series of access tunnels down to the depot... early reports indicate the objective was successfully hit," the MoD said.
There was no indication of any civilian impact in the operation late on Saturday and all the aircraft made a safe return, the defence officials confirmed.
The Typhoon fighters were backed up by a Voyager aerial refuelling aircraft.
Daesh - alternatively referred to as Daesh - established extremist governance over parts of both Syria and Iraq until 2019.
"This operation underscores our UK leadership, and resolve to operate in unison with allied nations, to eliminate any re-emergence of the terrorist group and their harmful and extremist ideologies in the region," the British Defence Secretary the minister remarked.
UK warplanes have carried out overwatch operations over Syrian airspace to "forestall any attempted resurgence" of Islamic State following its routing at the Baghuz confrontation in 2019, the authorities noted.
"I must thank every member of our armed forces who took part in this strike for their professionalism and their courage," the Defence Secretary added. "They were part of a great many British troops stationed over the holidays. This mission, to eliminate militants who pose a risk to our safety, highlights how UK forces are ready to step up, all year round, keeping Britain secure at home and influential overseas."
Last December, the American forces executed what it described as a "large-scale strike" on IS targets in Syria, following an ambush resulted in the deaths of two US servicemembers and a local interpreter in the Palmyra area.
The UN estimates IS still boasts roughly 5-7 thousand militants in Iraq and Syria.
