Royal Air Force Typhoon FGR4s have conducted a mission with French aircraft in a coordinated attack targeting an hidden munitions depot in Syria employed by the IS group, according to the UK Ministry of Defence.
The facility, pinpointed through reconnaissance, was assessed as housing weapons and explosive materials, the release indicated, and was positioned in mountainous terrain just above Palmyra in the heart of Syria.
"The RAF jets used laser-guided Paveway IV weapons to target a series of entry passages down to the depot... preliminary assessments indicate the objective was successfully hit," the ministry announced.
There was no evidence of any harm to civilians in the attack on Saturday evening and each participating jet returned safely, the ministry further stated.
The Typhoon FGR4s were supported by a Voyager refuelling tanker.
IS - referred to as Daesh - imposed extremist governance over parts of both Syria and Iraq until 2019.
"This strike demonstrates the UK's leading role, and commitment to stand shoulder to shoulder with our allies, to stamp out any resurgence of the terrorist group and their harmful and extremist ideologies in the Middle East," the British Defence Secretary the minister said.
British military aircraft have carried out surveillance missions over Syrian airspace to "forestall any efforts to regroup" of the group following its routing at the battle of Baghuz in 2019, the authorities noted.
"I extend gratitude to all the members of our armed forces involved in this operation for their expertise and their valour," Healey added. "They were part of thousands of UK service members deployed over Christmas and New Year. This action, to remove militants who pose a risk to our safety, demonstrates how UK forces are ready to step up, throughout the year, protecting the UK domestically and influential overseas."
During December, the US military conducted what it called a "massive strike" on Daesh sites in the country, following an ambush claimed the lives of two American soldiers and a civilian linguist in the Palmyra area.
The U.N. says IS still boasts between 5,000 and 7,000 combatants in Syria and Iraq.
