RAF Typhoon jets have operated alongside French warplanes in a coordinated attack on an hidden munitions depot in Syrian territory used by the IS group, per a report from the UK's MoD.
The location, located using intelligence, was assessed as storing arms and explosives, the statement said, and was located in mountains just to the north of the historic site of Palmyra in central Syria.
"Our aircraft used precision-guided Paveway IV munitions to hit a several entry passages down to the depot... early reports indicate the objective was successfully hit," the ministry announced.
There was no indication of any civilian casualties in the attack on Saturday evening and all the aircraft made a safe return, the ministry further stated.
The Typhoon fighters were backed up by a Voyager tanker plane.
Daesh - referred to as ISIS - enforced jihadist rule over significant areas in Iraq and Syria prior to its 2019 collapse.
"This operation demonstrates our UK leadership, and determination to stand shoulder to shoulder with our allies, to stamp out any revival of the terrorist group and their dangerous and violent ideologies in the Middle East," UK Defence Secretary the Defence Secretary remarked.
UK warplanes have conducted patrols over Syrian airspace to "prevent any efforts to regroup" of the group subsequent to its routing at the Baghuz confrontation in 2019, the authorities noted.
"I want to thank all the members of the UK armed forces who took part in this strike for their professionalism and their bravery," the Defence Secretary added. "Including them were numerous British personnel on duty over the holidays. This mission, to take out militants who pose a risk to our security, highlights how British military are prepared to act, throughout the year, protecting the UK domestically and powerful internationally."
During December, the US military carried out what it termed a "large-scale strike" on Islamic State objectives in the country, after an attack resulted in the deaths of two American soldiers and a local interpreter in the Palmyra area.
The United Nations estimates IS still maintains between 5,000 and 7,000 fighters in Iraq and Syria.
