British Air Force Typhoon FGR4s have joined forces with French warplanes in a combined operation against an underground arms cache in Syrian territory used by the Islamic State group (IS), per a report from the British defence ministry.
The location, located using intelligence, was thought to be storing arms and explosives, the statement said, and was located in mountains just north of Palmyra in Syria's central region.
"Our fighter planes used precision-guided Paveway IV munitions to hit a several entry passages providing entry to the site... preliminary assessments indicate the target was engaged successfully," the MoD said.
There was no sign of any civilian impact in the attack conducted Saturday night and every plane involved made a safe return, the defence officials confirmed.
The Typhoon fighters were assisted by a Voyager aerial refuelling aircraft.
IS - referred to as ISIS - enforced extremist governance over large swathes of Syria and Iraq until 2019.
"This operation shows British leadership, and determination to work closely with our allies, to eliminate any revival of Daesh and their dangerous and violent ideologies in the region," UK Defence Secretary the Defence Secretary said.
British military aircraft have performed overwatch operations over Syria to "forestall any attempted comeback" of the group following its defeat at the battle of Baghuz in 2019, the MoD reported.
"I must thank all the members of our armed forces involved in this strike for their skill and their bravery," Healey added. "They were part of a great many British troops on duty over Christmas and New Year. This operation, to eliminate terrorist threats who pose a risk to our safety, shows how British military are always on standby, throughout the year, keeping Britain secure domestically and strong abroad."
Last December, the US military carried out what it described as a "large-scale strike" against Daesh sites in Syria, subsequent to an assault killed two US troops and a civilian linguist in the Palmyra area.
The United Nations reports Daesh still boasts between 5,000 and 7,000 militants in both countries.
