British Air Force Typhoon jets have conducted a mission with French aircraft in a joint strike targeting an hidden munitions depot in Syrian territory employed by the IS group, per a report from the UK's MoD.
The site, identified by intelligence, was believed to be containing munitions and bombs, the release indicated, and was located in mountainous terrain just to the north of Palmyra in the heart of Syria.
"The RAF jets utilized Paveway IV guided bombs to target a series of approach shafts providing entry to the facility... preliminary assessments are that the objective was successfully hit," the ministry announced.
There was no indication of any harm to civilians in the strike on Saturday evening and all the aircraft returned safely, the ministry further stated.
The Typhoon fighters were backed up by a Voyager refuelling tanker.
Daesh - also known as the so-called Islamic State - enforced jihadist rule over significant areas in Iraq and Syria prior to its 2019 collapse.
"This action demonstrates British leadership, and commitment to stand shoulder to shoulder with our partners, to eliminate any re-emergence of Daesh and their dangerous and violent ideologies in the region," UK Defence Secretary the minister remarked.
RAF aircraft have conducted patrols over Syrian airspace to "deter any attempted resurgence" of the group after its defeat at the battle of Baghuz in the year 2019, the ministry said.
"I extend gratitude to all the members of the UK armed forces who took part in this operation for their skill and their valour," he said. "They were part of thousands of British troops on duty over the festive period. This action, to eliminate militants who endanger our safety, shows how UK forces are ready to step up, all year round, protecting the UK at home and influential overseas."
Last December, the United States armed forces executed what it described as a "major assault" against Daesh sites in Syria, subsequent to an attack killed two US troops and a local interpreter in the Palmyra area.
The United Nations estimates IS still has between 5,000 and 7,000 fighters in Syria and Iraq.
