British Air Force Typhoon fighter aircraft have joined forces with French aircraft in a combined operation against an subterranean weapons facility in Syrian territory employed by the IS group, according to the UK's MoD.
The facility, located using intelligence, was thought to be storing arms and explosives, the release indicated, and was situated in hills just above the historic site of Palmyra in Syria's central region.
"Our aircraft used precision-guided Paveway IV munitions to hit a several entry passages leading to the depot... initial indications suggest the objective was successfully hit," the ministry announced.
There was no indication of any civilian casualties in the operation conducted Saturday night and every plane involved returned safely, the MoD added.
The British jets were supported by a Voyager aerial refuelling aircraft.
Daesh - referred to as ISIS - imposed militant control over large swathes of Iraq and Syria prior to its 2019 collapse.
"This action demonstrates British leadership, and commitment to work closely with our partners, to stamp out any revival of the terrorist group and their dangerous and violent ideologies in the area," UK Defence Secretary the Defence Secretary remarked.
UK warplanes have performed patrols over Syria to "forestall any attempted resurgence" of IS subsequent to its defeat at the battle of Baghuz in 2019, the ministry said.
"I must thank every member of our armed forces involved in this mission for their professionalism and their valour," the Defence Secretary added. "They were among a great many British personnel deployed over the holidays. This operation, to take out militants who pose a risk to our way of life, highlights how UK forces are always on standby, all year round, keeping Britain secure domestically and strong abroad."
In December, the United States armed forces carried out what it described as a "major assault" on IS targets in Syria, following an attack resulted in the deaths of two US servicemembers and a civilian interpreter in the Palmyra area.
The United Nations reports Daesh still has between 5,000 and 7,000 fighters in both countries.
