British Air Force Typhoon FGR4s have operated alongside France's air force in a joint strike targeting an subterranean weapons facility in Syrian territory operated by the Daesh militant organization, per a report from the UK's MoD.
The location, pinpointed through intelligence, was thought to be housing weapons and explosive materials, the release indicated, and was situated in mountainous terrain just above Palmyra in central Syria.
"Our aircraft utilized laser-guided Paveway IV weapons to hit a several approach shafts providing entry to the facility... preliminary assessments are that the target was engaged successfully," the ministry announced.
There was no sign of any civilian casualties in the operation late on Saturday and each participating jet made a safe return, the MoD added.
The British jets were assisted by a Voyager refuelling tanker.
The Islamic State group - referred to as the so-called Islamic State - enforced extremist governance over significant areas in Syria and Iraq before its territorial defeat in 2019.
"This strike shows the UK's leading role, and resolve to stand shoulder to shoulder with allied nations, to eradicate any resurgence of IS and their violent and radical beliefs in the Middle East," UK Defence Secretary the Defence Secretary remarked.
British military aircraft have carried out overwatch operations over Syrian airspace to "deter any attempted resurgence" of the group after its defeat at the climactic battle in Baghuz in 2019, the authorities noted.
"I must thank the personnel of British forces involved in this strike for their skill and their valour," he added. "They were part of a great many British personnel stationed over the festive period. This mission, to take out militants who threaten our safety, shows how British military are ready to step up, throughout the year, keeping Britain secure at home and strong abroad."
In December, the United States armed forces carried out what it described as a "massive strike" on Islamic State objectives in the country, following an ambush resulted in the deaths of two American soldiers and a local interpreter in the Palmyra area.
The U.N. says Islamic State still has roughly 5-7 thousand fighters in both countries.
