Royal Air Force Typhoon jets have joined forces with France's air force in a combined operation on an subterranean weapons facility in Syria employed by the IS group, as stated by the UK's MoD.
The site, pinpointed through intelligence, was assessed as housing weapons and explosive materials, the release indicated, and was situated in mountains just to the north of the historic site of Palmyra in Syria's central region.
"Our aircraft used precision-guided Paveway IV munitions to target a number of access tunnels down to the depot... initial indications are that the target was engaged successfully," the ministry announced.
There was no sign of any civilian casualties in the strike conducted Saturday night and all the aircraft returned to base without incident, the ministry further stated.
The Typhoon FGR4s were assisted by a Voyager aerial refuelling aircraft.
Daesh - referred to as the so-called Islamic State - enforced militant control over parts of Syria and Iraq prior to its 2019 collapse.
"This action shows the UK's leading role, and resolve to stand shoulder to shoulder with our partners, to eradicate any resurgence of Daesh and their violent and radical beliefs in the area," UK Defence Secretary John Healey stated.
RAF aircraft have conducted overwatch operations over Syria to "deter any attempted comeback" of IS after its routing at the battle of Baghuz in 2019, the MoD reported.
"I must thank every member of the UK armed forces participating in this operation for their professionalism and their courage," he commented. "They were among numerous British troops stationed over Christmas and New Year. This action, to eliminate terrorist threats who endanger our security, shows how British military are ready to step up, all year round, ensuring Britain's security domestically and powerful internationally."
During December, the American forces conducted what it described as a "massive strike" targeting Daesh sites in the country, following an attack killed two US servicemembers and a civilian interpreter in Palmyra.
The UN estimates IS still maintains roughly 5-7 thousand militants in Syria and Iraq.
