British Air Force Typhoon fighter aircraft have joined forces with French warplanes in a coordinated attack against an underground arms cache in Syrian territory used by the Daesh militant organization, per a report from the UK Ministry of Defence.
The location, identified by reconnaissance, was thought to be storing arms and explosives, the statement said, and was situated in mountainous terrain just to the north of Palmyra in central Syria.
"Our aircraft used precision-guided Paveway IV munitions to strike a series of entry passages providing entry to the depot... initial indications suggest the strike was effective," the MoD said.
There was no indication of any civilian casualties in the attack late on Saturday and all the aircraft returned to base without incident, the ministry further stated.
The Typhoon FGR4s were backed up by a Voyager tanker plane.
The Islamic State group - also known as Daesh - established militant control over significant areas in Syria and Iraq before its territorial defeat in 2019.
"This strike underscores our UK leadership, and commitment to operate in unison with our partners, to stamp out any revival of Daesh and their harmful and extremist ideologies in the region," Britain's Defence Chief the Defence Secretary said.
RAF aircraft have conducted patrols over Syria to "deter any attempted resurgence" of Islamic State after its defeat at the Baghuz confrontation in 2019, the ministry said.
"I want to thank every member of the UK armed forces participating in this mission for their skill and their valour," Healey said. "They were part of numerous British troops deployed over Christmas and New Year. This action, to eliminate militants who threaten our security, demonstrates how our armed forces are ready to step up, all year round, keeping Britain secure domestically and influential overseas."
During December, the United States armed forces executed what it termed a "large-scale strike" against IS targets in the country, after an attack claimed the lives of two US troops and a civilian interpreter in Palmyra.
The UN reports IS still boasts between 5,000 and 7,000 combatants in Iraq and Syria.
