Royal Air Force Typhoon FGR4s have conducted a mission with French warplanes in a joint strike targeting an hidden munitions depot in Syrian territory employed by the IS group, per a report from the British defence ministry.
The facility, identified by surveillance, was thought to be housing weapons and explosive materials, the announcement noted, and was located in mountainous terrain just to the north of the ancient city of Palmyra in Syria's central region.
"Our aircraft employed Paveway IV guided bombs to strike a series of approach shafts providing entry to the facility... early reports are that the objective was successfully hit," officials stated.
There was no sign of any civilian casualties in the attack conducted Saturday night and every plane involved made a safe return, the ministry further stated.
The British jets were backed up by a Voyager refuelling tanker.
Daesh - referred to as Daesh - enforced jihadist rule over significant areas in Iraq and Syria before its territorial defeat in 2019.
"This operation underscores the UK's leading role, and commitment to stand shoulder to shoulder with our partners, to eradicate any resurgence of Daesh and their violent and radical beliefs in the Middle East," Britain's Defence Chief the minister remarked.
British military aircraft have carried out surveillance missions over Syria to "prevent any attempted comeback" of the group following its routing at the Baghuz confrontation in 2019, the authorities noted.
"I must thank all the members of the UK armed forces involved in this strike for their professionalism and their valour," he added. "Including them were thousands of UK service members stationed over Christmas and New Year. This action, to remove terrorist threats who endanger our safety, highlights how our armed forces are always on standby, throughout the year, keeping Britain secure at home and strong abroad."
During December, the American forces executed what it described as a "major assault" targeting IS targets in Syria, after an assault killed two US troops and a local interpreter in Palmyra.
The U.N. estimates Islamic State still has roughly 5-7 thousand militants in Iraq and Syria.
