British Air Force Typhoon FGR4s have operated alongside France's air force in a coordinated attack targeting an hidden munitions depot in Syria employed by the Islamic State group (IS), 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 situated in hills just above the ancient city of Palmyra in the heart of Syria.
"The RAF jets employed Paveway IV guided bombs to target a several entry passages providing entry to the site... initial indications suggest the target was engaged successfully," the ministry announced.
There was no evidence of any civilian casualties in the attack late on Saturday and every plane involved returned to base without incident, the defence officials confirmed.
The British jets were backed up by a Voyager refuelling tanker.
Daesh - also known as ISIS - established militant control over large swathes of both Syria and Iraq before its territorial defeat in 2019.
"This strike demonstrates British leadership, and resolve to stand shoulder to shoulder with our partners, to stamp out any revival of Daesh and their dangerous and violent ideologies in the area," UK Defence Secretary the Defence Secretary remarked.
British military aircraft have performed patrols over Syrian airspace to "prevent any attempted comeback" of Islamic State following its defeat at the battle of Baghuz in 2019, the MoD reported.
"I want to thank the personnel of British forces involved in this operation for their skill and their courage," the Defence Secretary added. "They were among numerous UK service members stationed over the holidays. This action, to eliminate militants who threaten our security, demonstrates how UK forces are always on standby, continuously, protecting the UK domestically and strong abroad."
During December, the United States armed forces executed what it described as a "major assault" targeting IS targets in the country, subsequent to an assault resulted in the deaths of two US servicemembers and a civilian interpreter in Palmyra.
The U.N. estimates IS still has roughly 5-7 thousand fighters in both countries.
