Royal Air Force Typhoon FGR4s have joined forces with French aircraft in a combined operation against an subterranean weapons facility in Syria operated by the Daesh militant organization, according to the British defence ministry.
The site, located using intelligence, was believed to be housing weapons and explosive materials, the statement said, and was positioned in mountainous terrain just to the north of the ancient city of Palmyra in the heart of Syria.
"Our aircraft utilized laser-guided Paveway IV weapons to strike a number of access tunnels leading to the site... early reports are that the objective was successfully hit," the MoD said.
There was no evidence of any civilian impact in the attack on Saturday evening and every plane involved returned to base without incident, the defence officials confirmed.
The British jets were backed up by a Voyager tanker plane.
Daesh - also known as Daesh - imposed extremist governance over large swathes of Syria and Iraq before its territorial defeat in 2019.
"This strike shows the UK's leading role, and determination to stand shoulder to shoulder with our partners, to eliminate any revival of Daesh and their dangerous and violent ideologies in the area," the British Defence Secretary the Defence Secretary remarked.
British military aircraft have conducted surveillance missions over Syria to "prevent any attempted comeback" of IS following its military defeat at the battle of Baghuz in 2019, the MoD reported.
"I must thank every member of British forces involved in this operation for their skill and their courage," Healey added. "Including them were numerous UK service members stationed over the festive period. This operation, to eliminate militants who threaten our security, demonstrates how British military are ready to step up, throughout the year, protecting the UK domestically and strong abroad."
During December, the American forces carried out what it termed a "major assault" on Daesh sites in the country, following an attack claimed the lives of two US troops and a local interpreter in Palmyra.
The UN says IS still boasts an estimated 5,000 to 7,000 militants in both countries.
