RAF Typhoon fighter aircraft have operated alongside French warplanes in a coordinated attack on an underground arms cache in Syrian territory operated by the Daesh militant organization, as stated by the British defence ministry.
The location, identified by surveillance, was thought to be containing munitions and bombs, the release indicated, and was located in mountainous terrain just north of the ancient city of Palmyra in Syria's central region.
"Our fighter planes utilized precision-guided Paveway IV munitions to target a number of approach shafts leading to the depot... preliminary assessments suggest the target was engaged successfully," the ministry announced.
There was no indication of any civilian impact in the operation on Saturday evening and each participating jet made a safe return, the defence officials confirmed.
The Typhoon FGR4s were supported by a Voyager tanker plane.
IS - referred to as the so-called Islamic State - imposed extremist governance over parts of both Syria and Iraq until 2019.
"This action shows British leadership, and determination to operate in unison with our allies, to stamp out any re-emergence of Daesh and their violent and radical beliefs in the Middle East," Britain's Defence Chief John Healey said.
British military aircraft have carried out surveillance missions over Syria to "prevent any attempted comeback" of IS following its military defeat at the Baghuz confrontation in the year 2019, the ministry said.
"I want to thank every member of British forces participating in this operation for their skill and their valour," he commented. "Including them were thousands of British troops on duty over Christmas and New Year. This mission, to eliminate terrorist threats who threaten our way of life, highlights how our armed forces are ready to step up, continuously, protecting the UK at home and strong abroad."
In December, the US military conducted what it termed a "major assault" on Islamic State objectives in the country, subsequent to an attack resulted in the deaths of two US servicemembers and a civilian linguist in Palmyra.
The UN reports IS still boasts between 5,000 and 7,000 combatants in both countries.
