RAF Typhoon fighter aircraft have joined forces with France's air force in a coordinated attack targeting an hidden munitions depot in Syria used by the IS group, per a report from the British defence ministry.
The facility, located using reconnaissance, was thought to be storing arms and explosives, the release indicated, and was situated in hills just above Palmyra in central Syria.
"The RAF jets utilized precision-guided Paveway IV munitions to strike a number of access tunnels providing entry to the site... initial indications indicate the strike was effective," the ministry announced.
There was no indication of any harm to civilians in the operation conducted Saturday night and all the aircraft made a safe return, the MoD added.
The British jets were backed up by a Voyager aerial refuelling aircraft.
Daesh - also known as Daesh - established jihadist rule over large swathes of both Syria and Iraq until 2019.
"This operation demonstrates our UK leadership, and commitment to work closely with our allies, to eradicate any revival of IS and their dangerous and violent ideologies in the region," UK Defence Secretary the Defence Secretary stated.
UK warplanes have carried out patrols over Syrian airspace to "forestall any attempted resurgence" of IS subsequent to its military defeat at the Baghuz confrontation in 2019, the authorities noted.
"I want to thank all the members of our armed forces participating in this operation for their expertise and their bravery," he added. "They were part of numerous UK service members on duty over the festive period. This operation, to take out militants who threaten our safety, highlights how British military are ready to step up, continuously, protecting the UK domestically and strong abroad."
During December, the United States armed forces conducted what it described as a "large-scale strike" against Islamic State objectives in the country, following an ambush resulted in the deaths of two American soldiers and a civilian linguist in Palmyra.
The United Nations says IS still has an estimated 5,000 to 7,000 combatants in both countries.
