Royal Air Force Typhoon fighter aircraft have operated alongside French aircraft in a combined operation on an underground arms cache in Syria employed by the Daesh militant organization, according to the UK's MoD.
The location, pinpointed through reconnaissance, was believed to be housing weapons and explosive materials, the release indicated, and was located in mountainous terrain just above the historic site of Palmyra in Syria's central region.
"Our fighter planes utilized laser-guided Paveway IV weapons to strike a several approach shafts down to the depot... early reports suggest the objective was successfully hit," the ministry announced.
There was no indication of any civilian casualties in the attack on Saturday evening and each participating jet made a safe return, the ministry further stated.
The Typhoon FGR4s were assisted by a Voyager refuelling tanker.
The Islamic State group - referred to as Daesh - enforced jihadist rule over large swathes of Iraq and Syria until 2019.
"This action shows our UK leadership, and commitment to operate in unison with our partners, to eliminate any revival of Daesh and their violent and radical beliefs in the area," UK Defence Secretary the minister remarked.
UK warplanes have carried out patrols over Syria to "forestall any attempted resurgence" of Islamic State subsequent to its routing at the Baghuz confrontation in 2019, the authorities noted.
"I must thank all the members of British forces who took part in this strike for their skill and their bravery," the Defence Secretary added. "Including them were a great many British troops deployed over Christmas and New Year. This action, to eliminate militants who threaten our way of life, highlights how British military are always on standby, throughout the year, keeping Britain secure domestically and influential overseas."
In December, the US military conducted what it termed a "massive strike" on Daesh sites in the country, subsequent to an attack killed two US troops and a civilian interpreter in Palmyra.
The United Nations reports Daesh still maintains between 5,000 and 7,000 combatants in Iraq and Syria.
