British Air Force Typhoon FGR4s have joined forces with France's air force in a combined operation on an hidden munitions depot in Syrian territory operated by the IS group, as stated by the UK's MoD.
The facility, pinpointed through reconnaissance, was thought to be storing arms and explosives, the release indicated, and was located in mountains just north of Palmyra in central Syria.
"Our fighter planes employed laser-guided Paveway IV weapons to strike a series of approach shafts down to the depot... early reports indicate the target was engaged successfully," the ministry announced.
There was no evidence of any civilian casualties in the operation conducted Saturday night and each participating jet returned to base without incident, the defence officials confirmed.
The Typhoon FGR4s were assisted by a Voyager tanker plane.
The Islamic State group - also known as Daesh - established militant control over large swathes of Iraq and Syria before its territorial defeat in 2019.
"This operation shows our UK leadership, and resolve to stand shoulder to shoulder with our partners, to stamp out any re-emergence of Daesh and their violent and radical beliefs in the area," UK Defence Secretary John Healey remarked.
UK warplanes have conducted surveillance missions over Syria to "forestall any attempted resurgence" of the group after its military defeat at the Baghuz confrontation in 2019, the authorities noted.
"I must thank the personnel of the UK armed forces participating in this mission for their expertise and their bravery," Healey said. "They were part of thousands of British personnel on duty over the holidays. This mission, to remove dangerous terrorists who threaten our way of life, shows how British military are prepared to act, all year round, keeping Britain secure domestically and powerful internationally."
Last December, the American forces carried out what it called a "major assault" on Daesh sites in Syria, following an assault resulted in the deaths of two US troops and a civilian interpreter in the Palmyra area.
The United Nations estimates Islamic State still has between 5,000 and 7,000 combatants in Iraq and Syria.
