Royal Air Force Typhoon FGR4s have joined forces with French aircraft in a combined operation on an underground arms cache in Syrian territory operated by the IS group, as stated by the British defence ministry.
The site, pinpointed through surveillance, was thought to be containing munitions and bombs, the announcement noted, and was situated in hills just to the north of the historic site of Palmyra in Syria's central region.
"Our aircraft utilized Paveway IV guided bombs to hit a several approach shafts leading to the depot... early reports are that the target was engaged successfully," officials stated.
There was no evidence of any civilian casualties in the strike late on Saturday and all the aircraft returned to base without incident, the MoD added.
The Typhoon fighters were assisted by a Voyager tanker plane.
The Islamic State group - alternatively referred to as ISIS - enforced militant control over parts of both Syria and Iraq until 2019.
"This action shows the UK's leading role, and resolve to work closely with our partners, to stamp out any re-emergence of IS and their violent and radical beliefs in the region," UK Defence Secretary the Defence Secretary said.
UK warplanes have performed surveillance missions over Syria to "forestall any attempted resurgence" of the group after its military defeat at the climactic battle in Baghuz in the year 2019, the authorities noted.
"I must thank the personnel of the UK armed forces who took part in this mission for their skill and their valour," the Defence Secretary added. "Including them were thousands of British personnel deployed over the holidays. This mission, to remove dangerous terrorists who endanger our safety, highlights how UK forces are ready to step up, continuously, keeping Britain secure within its borders and powerful internationally."
In December, the United States armed forces conducted what it described as a "massive strike" on Daesh sites in the country, following an ambush claimed the lives of two US servicemembers and a local interpreter in Palmyra.
The U.N. reports IS still has roughly 5-7 thousand militants in both countries.
