RAF Typhoon FGR4s have conducted a mission with French aircraft in a coordinated attack on an underground arms cache in Syria employed by the IS group, per a report from the British defence ministry.
The location, located using intelligence, was assessed as storing arms and explosives, the statement said, and was positioned in hills just to the north of Palmyra in Syria's central region.
"Our fighter planes utilized Paveway IV guided bombs to hit a series of access tunnels down to the facility... early reports suggest the strike was effective," the ministry announced.
There was no indication of any harm to civilians in the attack on Saturday evening and every plane involved returned safely, the ministry further stated.
The Typhoon fighters were backed up by a Voyager tanker plane.
IS - alternatively referred to as the so-called Islamic State - imposed militant control over large swathes of Iraq and Syria before its territorial defeat in 2019.
"This operation underscores British leadership, and determination to stand shoulder to shoulder with our allies, to stamp out any resurgence of IS and their dangerous and violent ideologies in the area," UK Defence Secretary the Defence Secretary remarked.
British military aircraft have conducted overwatch operations over Syria to "prevent any attempted resurgence" of the group subsequent to its military defeat at the Baghuz confrontation in 2019, the authorities noted.
"I extend gratitude to all the members of British forces participating in this operation for their skill and their valour," Healey commented. "Including them were thousands of UK service members stationed over the holidays. This operation, to eliminate terrorist threats who threaten our safety, demonstrates how our armed forces are ready to step up, continuously, protecting the UK at home and powerful internationally."
Last December, the US military executed what it termed a "large-scale strike" targeting IS targets in Syria, following an ambush killed two American soldiers and a civilian linguist in the Palmyra area.
The United Nations reports Daesh still boasts between 5,000 and 7,000 combatants in Iraq and Syria.
