British Air Force Typhoon jets have joined forces with France's air force in a coordinated attack on an underground arms cache in Syrian territory employed by the Islamic State group (IS), per a report from the UK's MoD.
The facility, located using intelligence, was thought to be storing arms and explosives, the release indicated, and was situated in mountains just to the north of Palmyra in central Syria.
"Our fighter planes employed Paveway IV guided bombs to strike a several access tunnels leading to the depot... initial indications suggest the strike was effective," the ministry announced.
There was no evidence of any harm to civilians in the attack conducted Saturday night and all the aircraft made a safe return, the ministry further stated.
The Typhoon FGR4s were assisted by a Voyager refuelling tanker.
Daesh - also known as the so-called Islamic State - established militant control over large swathes of both Syria and Iraq prior to its 2019 collapse.
"This action underscores British leadership, and determination to work closely with allied nations, to eliminate any resurgence of Daesh and their dangerous and violent ideologies in the area," UK Defence Secretary John Healey remarked.
UK warplanes have conducted surveillance missions over Syrian airspace to "prevent any efforts to regroup" of the group after its military defeat at the Baghuz confrontation in the year 2019, the authorities noted.
"I want to thank every member of our armed forces participating in this strike for their skill and their bravery," he added. "Including them were thousands of British troops stationed over the festive period. This operation, to eliminate militants who pose a risk to our way of life, highlights how British military are ready to step up, continuously, protecting the UK at home and influential overseas."
During December, the American forces executed what it termed a "massive strike" targeting Daesh sites in the country, following an assault killed two US troops and a civilian interpreter in Palmyra.
The United Nations reports Daesh still has an estimated 5,000 to 7,000 fighters in Syria and Iraq.
