British Air Force Typhoon jets have joined forces with French warplanes in a coordinated attack against an hidden munitions depot in Syrian territory used by the IS group, per a report from the UK's MoD.
The site, located using intelligence, was thought to be storing arms and explosives, the statement said, and was located in mountains just above Palmyra in the heart of Syria.
"Our aircraft utilized laser-guided Paveway IV weapons to hit a series of entry passages down to the facility... initial indications suggest the strike was effective," officials stated.
There was no evidence of any civilian casualties in the attack conducted Saturday night and all the aircraft made a safe return, the ministry further stated.
The Typhoon fighters were backed up by a Voyager aerial refuelling aircraft.
Daesh - referred to as Daesh - established extremist governance over large swathes of Iraq and Syria before its territorial defeat in 2019.
"This operation underscores our UK leadership, and commitment to stand shoulder to shoulder with our allies, to eradicate any resurgence of Daesh and their violent and radical beliefs in the region," UK Defence Secretary the minister remarked.
UK warplanes have performed patrols over Syria to "forestall any attempted comeback" of the group subsequent to its routing at the Baghuz confrontation in 2019, the authorities noted.
"I want to thank every member of the UK armed forces who took part in this operation for their expertise and their courage," he added. "They were part of a great many British personnel stationed over Christmas and New Year. This operation, to remove militants who threaten our security, shows how British military are always on standby, continuously, protecting the UK at home and influential overseas."
Last December, the United States armed forces executed what it called a "massive strike" against IS targets in the country, after an attack killed two American soldiers and a civilian linguist in the Palmyra area.
The U.N. says IS still boasts between 5,000 and 7,000 combatants in Syria and Iraq.
