British Air Force Typhoon FGR4s have joined forces with French aircraft in a coordinated attack on an underground arms cache in Syrian territory employed by the IS group, as stated by the British defence ministry.
The location, located using reconnaissance, was assessed as containing munitions and bombs, the announcement noted, and was situated in mountains just north of Palmyra in Syria's central region.
"Our fighter planes used precision-guided Paveway IV munitions to hit a series of entry passages down to the site... early reports suggest the objective was successfully hit," the ministry announced.
There was no evidence of any civilian casualties in the operation on Saturday evening and every plane involved made a safe return, the MoD added.
The Typhoon FGR4s were assisted by a Voyager tanker plane.
The Islamic State group - also known as the so-called Islamic State - enforced jihadist rule over large swathes of Syria and Iraq prior to its 2019 collapse.
"This strike demonstrates our UK leadership, and determination to work closely with our allies, to eliminate any re-emergence of IS and their dangerous and violent ideologies in the region," Britain's Defence Chief the Defence Secretary remarked.
UK warplanes have carried out surveillance missions over Syria to "forestall any efforts to regroup" of IS after its routing at the battle of Baghuz in 2019, the MoD reported.
"I must thank every member of our armed forces involved in this strike for their expertise and their valour," he commented. "Including them were numerous British troops deployed over Christmas and New Year. This operation, to eliminate militants who threaten our safety, highlights how British military are prepared to act, all year round, ensuring Britain's security domestically and influential overseas."
In December, the US military executed what it called a "massive strike" targeting Daesh sites in Syria, following an assault killed two US servicemembers and a civilian linguist in the Palmyra area.
The U.N. reports Daesh still maintains roughly 5-7 thousand militants in Iraq and Syria.
