RAF Typhoon FGR4s have joined forces with France's air force in a coordinated attack targeting an hidden munitions depot in Syria operated by the IS group, per a report from the UK Ministry of Defence.
The site, pinpointed through intelligence, was thought to be housing weapons and explosive materials, the statement said, and was situated in mountainous terrain just north of the ancient city of Palmyra in central Syria.
"Our fighter planes employed Paveway IV guided bombs to hit a series of approach shafts leading to the facility... early reports indicate the target was engaged successfully," officials stated.
There was no sign of any harm to civilians in the attack late on Saturday and all the aircraft made a safe return, the ministry further stated.
The British jets were supported by a Voyager refuelling tanker.
The Islamic State group - alternatively referred to as the so-called Islamic State - imposed militant control over parts of Syria and Iraq before its territorial defeat in 2019.
"This operation demonstrates our UK leadership, and determination to work closely with allied nations, to eliminate any revival of Daesh and their harmful and extremist ideologies in the region," the British Defence Secretary the minister said.
British military aircraft have carried out patrols over Syria to "deter any efforts to regroup" of IS subsequent to its military defeat at the Baghuz confrontation in 2019, the MoD reported.
"I extend gratitude to the personnel of British forces who took part in this mission for their skill and their bravery," he added. "Including them were a great many UK service members on duty over the holidays. This operation, to remove dangerous terrorists who pose a risk to our way of life, highlights how our armed forces are ready to step up, continuously, protecting the UK domestically and powerful internationally."
