RAF Typhoon fighter aircraft have operated alongside France's air force in a coordinated attack on an hidden munitions depot in Syrian territory used by the Daesh militant organization, as stated by the British defence ministry.
The site, identified by surveillance, was assessed as housing weapons and explosive materials, the release indicated, and was positioned in mountains just to the north of the historic site of Palmyra in Syria's central region.
"The RAF jets utilized precision-guided Paveway IV munitions to strike a series of approach shafts down to the depot... initial indications suggest the objective was successfully hit," the MoD said.
There was no indication of any harm to civilians in the operation late on Saturday and every plane involved returned safely, the ministry further stated.
The British jets were supported by a Voyager refuelling tanker.
The Islamic State group - also known as the so-called Islamic State - enforced militant control over significant areas in Iraq and Syria prior to its 2019 collapse.
"This action demonstrates the UK's leading role, and determination to work closely with our partners, to eliminate any revival of IS and their violent and radical beliefs in the Middle East," UK Defence Secretary John Healey stated.
UK warplanes have performed overwatch operations over Syrian airspace to "forestall any attempted resurgence" of the group after its military defeat at the battle of Baghuz in 2019, the ministry said.
"I must thank all the members of our armed forces involved in this strike for their expertise and their bravery," he added. "Including them were a great many UK service members deployed over the holidays. This mission, to eliminate dangerous terrorists who pose a risk to our safety, demonstrates how UK forces are ready to step up, all year round, protecting the UK at home and powerful internationally."
During December, the American forces executed what it termed a "large-scale strike" on Islamic State objectives in the country, following an attack resulted in the deaths of two American soldiers and a civilian linguist in the Palmyra area.
The UN says Islamic State still has an estimated 5,000 to 7,000 fighters in Syria and Iraq.
