British Air Force Typhoon jets have joined forces with French aircraft in a joint strike on an hidden munitions depot in Syrian territory employed by the Daesh militant organization, as stated by the UK's MoD.
The facility, located using surveillance, was believed to be storing arms and explosives, the announcement noted, and was situated in hills just above Palmyra in Syria's central region.
"Our aircraft used Paveway IV guided bombs to target a series of entry passages providing entry to the depot... early reports indicate the strike was effective," the ministry announced.
There was no indication of any harm to civilians in the operation on Saturday evening and every plane involved returned safely, the defence officials confirmed.
The Typhoon FGR4s were backed up by a Voyager refuelling tanker.
The Islamic State group - referred to as ISIS - imposed militant control over significant areas in both Syria and Iraq until 2019.
"This action shows British leadership, and commitment to operate in unison with our partners, to eliminate any resurgence of the terrorist group and their violent and radical beliefs in the region," UK Defence Secretary John Healey remarked.
RAF aircraft have conducted patrols over Syrian airspace to "prevent any attempted comeback" of Islamic State after its routing at the battle of Baghuz in 2019, the ministry said.
"I must thank all the members of British forces participating in this strike for their expertise and their courage," the Defence Secretary said. "They were part of numerous British personnel stationed over the festive period. This operation, to remove militants who threaten our way of life, shows how UK forces are ready to step up, throughout the year, protecting the UK at home and influential overseas."
Last December, the American forces executed what it termed a "massive strike" targeting Daesh sites in Syria, subsequent to an ambush resulted in the deaths of two US servicemembers and a local interpreter in the Palmyra area.
The United Nations reports Daesh still maintains between 5,000 and 7,000 combatants in both countries.
