RAF Typhoon FGR4s have operated alongside French warplanes in a coordinated attack targeting an underground arms cache in Syrian territory employed by the Islamic State group (IS), as stated by the British defence ministry.
The site, located using reconnaissance, was believed to be containing munitions and bombs, the release indicated, and was situated in mountainous terrain just above the ancient city of Palmyra in central Syria.
"Our aircraft used Paveway IV guided bombs to strike a number of approach shafts leading to the facility... preliminary assessments are that the objective was successfully hit," officials stated.
There was no indication of any civilian casualties in the attack on Saturday evening and all the aircraft made a safe return, the ministry further stated.
The Typhoon FGR4s were supported by a Voyager tanker plane.
Daesh - alternatively referred to as Daesh - imposed militant control over significant areas in Iraq and Syria until 2019.
"This action demonstrates our UK leadership, and resolve to operate in unison with our partners, to eliminate any resurgence of the terrorist group and their violent and radical beliefs in the Middle East," the British Defence Secretary John Healey remarked.
British military aircraft have conducted patrols over Syria to "prevent any attempted comeback" of the group subsequent to its routing at the Baghuz confrontation in 2019, the ministry said.
"I must thank the personnel of British forces participating in this strike for their skill and their valour," Healey added. "Including them were numerous British personnel deployed over the festive period. This operation, to take out militants who pose a risk to our security, demonstrates how our armed forces are ready to step up, throughout the year, protecting the UK within its borders and powerful internationally."
In December, the United States armed forces conducted what it described as a "major assault" on Daesh sites in the country, subsequent to an attack resulted in the deaths of two US troops and a civilian linguist in Palmyra.
The UN reports Daesh still maintains roughly 5-7 thousand combatants in Iraq and Syria.
