British Air Force Typhoon FGR4s have joined forces with France's air force in a joint strike against an subterranean weapons facility in Syria operated by the Islamic State group (IS), as stated by the UK's MoD.
The location, located using surveillance, was believed to be storing arms and explosives, the release indicated, and was positioned in mountains just north of the historic site of Palmyra in Syria's central region.
"The RAF jets employed laser-guided Paveway IV weapons to hit a series of approach shafts leading to the site... early reports indicate the objective was successfully hit," the MoD said.
There was no sign of any civilian impact in the attack on Saturday evening and each participating jet returned to base without incident, the MoD added.
The Typhoon fighters were backed up by a Voyager refuelling tanker.
Daesh - referred to as ISIS - imposed extremist governance over large swathes of Iraq and Syria before its territorial defeat in 2019.
"This action underscores British leadership, and commitment to operate in unison with our allies, to eliminate any revival of the terrorist group and their dangerous and violent ideologies in the Middle East," Britain's Defence Chief the Defence Secretary remarked.
RAF aircraft have performed overwatch operations over Syria to "forestall any attempted resurgence" of Islamic State after its defeat at the battle of Baghuz in the year 2019, the ministry said.
"I must thank every member of the UK armed forces involved in this operation for their professionalism and their bravery," he commented. "They were among a great many British troops on duty over the festive period. This mission, to take out dangerous terrorists who threaten our way of life, shows how British military are prepared to act, all year round, keeping Britain secure at home and strong abroad."
During December, the American forces carried out what it termed a "massive strike" against Daesh sites in the country, after an attack claimed the lives of two US servicemembers and a civilian linguist in the Palmyra area.
The United Nations reports Daesh still maintains between 5,000 and 7,000 fighters in Iraq and Syria.
