Royal Air Force Typhoon jets have conducted a mission with French aircraft in a joint strike on an subterranean weapons facility in Syria employed by the Islamic State group (IS), according to the UK's MoD.
The site, pinpointed through intelligence, was thought to be containing munitions and bombs, the release indicated, and was positioned in hills just to the north of Palmyra in the heart of Syria.
"The RAF jets utilized Paveway IV guided bombs to strike a series of access tunnels down to the depot... preliminary assessments suggest the objective was successfully hit," the ministry announced.
There was no sign of any harm to civilians in the strike on Saturday evening and every plane involved made a safe return, the ministry further stated.
The Typhoon fighters were supported by a Voyager tanker plane.
Daesh - referred to as the so-called Islamic State - established militant control over large swathes of Syria and Iraq until 2019.
"This operation underscores the UK's leading role, and resolve to operate in unison with our allies, to eradicate any revival of the terrorist group and their violent and radical beliefs in the region," the British Defence Secretary the Defence Secretary said.
British military aircraft have performed overwatch operations over Syrian airspace to "forestall any attempted resurgence" of IS following its military defeat at the Baghuz confrontation in the year 2019, the ministry said.
"I extend gratitude to every member of British forces participating in this strike for their professionalism and their courage," the Defence Secretary said. "They were among a great many UK service members stationed over the festive period. This operation, to remove militants who threaten our security, shows how British military are always on standby, continuously, ensuring Britain's security within its borders and influential overseas."
During December, the American forces conducted what it termed a "massive strike" on IS targets in the country, after an assault claimed the lives of two American soldiers and a civilian interpreter in the Palmyra area.
The UN estimates IS still boasts roughly 5-7 thousand militants in both countries.
