Royal Air Force Typhoon fighter aircraft have conducted a mission 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 site, pinpointed through surveillance, was assessed as storing arms and explosives, the statement said, and was situated in mountainous terrain just north of Palmyra in central Syria.
"Our fighter planes employed Paveway IV guided bombs to hit a series of approach shafts down to the facility... initial indications are that the target was engaged successfully," the MoD said.
There was no indication of any civilian casualties in the attack conducted Saturday night and each participating jet returned to base without incident, the ministry further stated.
The Typhoon FGR4s were backed up by a Voyager tanker plane.
Daesh - referred to as Daesh - enforced jihadist rule over large swathes of Iraq and Syria before its territorial defeat in 2019.
"This operation shows our UK leadership, and resolve to work closely with our allies, to eliminate any resurgence of the terrorist group and their violent and radical beliefs in the region," UK Defence Secretary the minister remarked.
RAF aircraft have conducted patrols over Syrian airspace to "forestall any attempted resurgence" of the group following its defeat at the Baghuz confrontation in 2019, the authorities noted.
"I want to thank the personnel of the UK armed forces who took part in this operation for their expertise and their valour," the Defence Secretary commented. "They were among thousands of British personnel deployed over Christmas and New Year. This action, to take out terrorist threats who endanger our safety, shows how UK forces are always on standby, continuously, ensuring Britain's security within its borders and strong abroad."
In December, the American forces carried out what it termed a "large-scale strike" targeting IS targets in the country, following an assault claimed the lives of two US servicemembers and a civilian interpreter in Palmyra.
The U.N. says Islamic State still maintains between 5,000 and 7,000 fighters in Iraq and Syria.
