RAF Typhoon fighter aircraft have joined forces with French aircraft in a joint strike targeting an underground arms cache in Syria operated by the Daesh militant organization, as stated by the UK's MoD.
The location, identified by reconnaissance, was believed to be housing weapons and explosive materials, the release indicated, and was positioned in mountainous terrain just north of the historic site of Palmyra in Syria's central region.
"Our fighter planes utilized Paveway IV guided bombs to hit a series of approach shafts providing entry to the depot... initial indications are that the strike was effective," the ministry announced.
There was no sign of any civilian impact in the operation late on Saturday and all the aircraft returned safely, the ministry further stated.
The Typhoon fighters were backed up by a Voyager tanker plane.
The Islamic State group - also known as Daesh - imposed jihadist rule over large swathes of Syria and Iraq until 2019.
"This operation underscores the UK's leading role, and resolve to stand shoulder to shoulder with our partners, to stamp out any re-emergence of the terrorist group and their violent and radical beliefs in the Middle East," Britain's Defence Chief the Defence Secretary stated.
British military aircraft have performed overwatch operations over Syrian airspace to "forestall any efforts to regroup" of Islamic State following its military defeat at the Baghuz confrontation in 2019, the ministry said.
"I want to thank all the members of our armed forces involved in this mission for their professionalism and their bravery," he said. "They were part of numerous British troops on duty over the festive period. This operation, to remove militants who endanger our security, highlights how British military are always on standby, throughout the year, keeping Britain secure within its borders and strong abroad."
During December, the United States armed forces carried out what it termed a "massive strike" against Daesh sites in Syria, subsequent to an assault claimed the lives of two American soldiers and a civilian interpreter in the Palmyra area.
The United Nations says Daesh still has an estimated 5,000 to 7,000 combatants in Syria and Iraq.
