British Air Force Typhoon FGR4s have operated alongside French aircraft in a combined operation on an underground arms cache in Syrian territory operated by the Daesh militant organization, according to the UK Ministry of Defence.
The facility, pinpointed through surveillance, was believed to be containing munitions and bombs, the release indicated, and was located in mountains just north of Palmyra in Syria's central region.
"The RAF jets used laser-guided Paveway IV weapons to strike a series of entry passages providing entry to the site... preliminary assessments suggest the objective was successfully hit," officials stated.
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 British jets were backed up by a Voyager aerial refuelling aircraft.
Daesh - also known as the so-called Islamic State - imposed jihadist rule over parts of Iraq and Syria before its territorial defeat in 2019.
"This action demonstrates our UK leadership, and resolve to stand shoulder to shoulder with allied nations, to eradicate any re-emergence of IS and their dangerous and violent ideologies in the area," UK Defence Secretary John Healey remarked.
British military aircraft have conducted overwatch operations over Syria to "deter any efforts to regroup" of IS following its military defeat at the Baghuz confrontation in 2019, the authorities noted.
"I extend gratitude to all the members of British forces participating in this mission for their expertise and their valour," the Defence Secretary commented. "They were part of numerous UK service members deployed over the festive period. This operation, to eliminate militants who threaten our way of life, highlights how UK forces are ready to step up, all year round, keeping Britain secure domestically and strong abroad."
In December, the United States armed forces carried out what it termed a "large-scale strike" targeting Daesh sites in Syria, following an attack killed two US servicemembers and a civilian linguist in Palmyra.
The United Nations estimates Daesh still maintains an estimated 5,000 to 7,000 militants in both countries.
