RAF Typhoon FGR4s have operated alongside France's air force in a coordinated attack targeting an hidden munitions depot in Syria operated by the Islamic State group (IS), as stated by the UK's MoD.
The location, identified by intelligence, was believed to be storing arms and explosives, the statement said, and was positioned in mountains just to the north of the historic site of Palmyra in the heart of Syria.
"Our aircraft utilized Paveway IV guided bombs to target a series of approach shafts providing entry to the site... initial indications suggest the strike was effective," the ministry announced.
There was no evidence of any civilian casualties in the operation on Saturday evening and every plane involved made a safe return, the defence officials confirmed.
The Typhoon fighters were backed up by a Voyager aerial refuelling aircraft.
The Islamic State group - alternatively referred to as the so-called Islamic State - imposed militant control over parts of both Syria and Iraq before its territorial defeat in 2019.
"This strike shows the UK's leading role, and commitment to work closely with our partners, to eliminate any re-emergence of the terrorist group and their harmful and extremist ideologies in the Middle East," the British Defence Secretary the Defence Secretary stated.
British military aircraft have conducted patrols over Syrian airspace to "forestall any efforts to regroup" of Islamic State after its defeat at the Baghuz confrontation in 2019, the MoD reported.
"I must thank the personnel of our armed forces involved in this strike for their professionalism and their valour," the Defence Secretary commented. "They were among a great many British personnel on duty over the festive period. This mission, to eliminate militants who endanger our security, shows how British military are ready to step up, throughout the year, protecting the UK at home and powerful internationally."
