Royal Air Force Typhoon jets have conducted a mission with French aircraft in a combined operation against an hidden munitions depot in Syrian territory employed by the Islamic State group (IS), according to the UK's MoD.
The facility, identified by intelligence, was believed to be storing arms and explosives, the release indicated, and was located in mountains just to the north of Palmyra in Syria's central region.
"Our fighter planes used laser-guided Paveway IV weapons to target a several approach shafts providing entry to the facility... early reports indicate the objective was successfully hit," officials stated.
There was no indication of any civilian impact in the attack conducted Saturday night and all the aircraft made a safe return, the ministry further stated.
The Typhoon fighters were assisted by a Voyager refuelling tanker.
IS - also known as ISIS - enforced extremist governance over large swathes of both Syria and Iraq until 2019.
"This action shows our UK leadership, and commitment to work closely with our partners, to eliminate any resurgence of Daesh and their dangerous and violent ideologies in the area," UK Defence Secretary John Healey remarked.
RAF aircraft have performed surveillance missions over Syrian airspace to "forestall any efforts to regroup" of IS subsequent to its military defeat at the Baghuz confrontation in the year 2019, the authorities noted.
"I must thank all the members of British forces who took part in this mission for their skill and their bravery," he said. "They were part of a great many UK service members deployed over the holidays. This operation, to take out dangerous terrorists who endanger our way of life, demonstrates how British military are ready to step up, throughout the year, ensuring Britain's security at home and influential overseas."
Last December, the United States armed forces executed what it termed a "large-scale strike" on Islamic State objectives in the country, after an assault claimed the lives of two American soldiers and a civilian linguist in the Palmyra area.
The U.N. says Daesh still maintains an estimated 5,000 to 7,000 fighters in both countries.
