British Air Force Typhoon fighter aircraft have conducted a mission with France's air force in a combined operation against an subterranean weapons facility in Syrian territory operated by the Daesh militant organization, per a report from the UK's MoD.
The location, identified by intelligence, was assessed as storing arms and explosives, the announcement noted, and was situated in mountains just north of the ancient city of Palmyra in Syria's central region.
"The RAF jets employed laser-guided Paveway IV weapons to target a series of approach shafts providing entry to the facility... early reports suggest the target was engaged successfully," the ministry announced.
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 British jets were assisted by a Voyager refuelling tanker.
The Islamic State group - also known as the so-called Islamic State - imposed jihadist rule over significant areas in both Syria and Iraq until 2019.
"This action shows British leadership, and commitment to work closely with our partners, to eliminate any re-emergence of IS and their harmful and extremist ideologies in the area," UK Defence Secretary the Defence Secretary remarked.
British military aircraft have conducted overwatch operations over Syria to "forestall any efforts to regroup" of IS subsequent to its routing at the climactic battle in Baghuz in 2019, the ministry said.
"I extend gratitude to all the members of the UK armed forces involved in this mission for their skill and their valour," he said. "They were part of numerous British troops deployed over the festive period. This action, to remove terrorist threats who pose a risk to our way of life, shows how UK forces are always on standby, continuously, keeping Britain secure within its borders and influential overseas."
During December, the American forces carried out what it termed a "large-scale strike" targeting Daesh sites in the country, subsequent to an attack resulted in the deaths of two US servicemembers and a civilian interpreter in Palmyra.
The UN says Islamic State still maintains roughly 5-7 thousand fighters in both countries.
