Royal Air Force Typhoon FGR4s have joined forces with France's air force in a combined operation on an underground arms cache in Syrian territory operated by the Islamic State group (IS), according to the British defence ministry.
The location, identified by surveillance, was assessed as containing munitions and bombs, the announcement noted, and was located in hills just above Palmyra in central Syria.
"Our fighter planes used precision-guided Paveway IV munitions to target a several entry passages providing entry to the site... early reports indicate the objective was successfully hit," the MoD said.
There was no indication of any civilian impact in the operation conducted Saturday night and all the aircraft made a safe return, the MoD added.
The Typhoon fighters were backed up by a Voyager tanker plane.
Daesh - referred to as the so-called Islamic State - enforced extremist governance over parts of both Syria and Iraq before its territorial defeat in 2019.
"This operation underscores our UK leadership, and commitment to work closely with allied nations, to eradicate any revival of Daesh and their dangerous and violent ideologies in the area," UK Defence Secretary the minister stated.
RAF aircraft have carried out patrols over Syrian airspace to "forestall any attempted resurgence" of IS following its defeat at the Baghuz confrontation in the year 2019, the ministry said.
"I extend gratitude to the personnel of British forces participating in this strike for their professionalism and their courage," Healey said. "Including them were numerous British personnel stationed over the festive period. This operation, to remove militants who threaten our way of life, shows how our armed forces are ready to step up, all year round, keeping Britain secure domestically and influential overseas."
In December, the American forces conducted what it termed a "massive strike" on Islamic State objectives in Syria, after an ambush killed two US servicemembers and a local interpreter in the Palmyra area.
The United Nations reports Daesh still maintains an estimated 5,000 to 7,000 fighters in both countries.
