RAF Typhoon jets have conducted a mission with French warplanes in a coordinated attack against an subterranean weapons facility in Syria employed by the IS group, as stated by the British defence ministry.
The location, located using reconnaissance, was assessed as containing munitions and bombs, the announcement noted, and was situated in mountains just to the north of the historic site of Palmyra in Syria's central region.
"Our fighter planes used precision-guided Paveway IV munitions to strike a several access tunnels leading to the site... initial indications indicate the objective was successfully hit," the ministry announced.
There was no sign of any harm to civilians in the strike on Saturday evening and every plane involved returned safely, the defence officials confirmed.
The Typhoon fighters were assisted by a Voyager refuelling tanker.
The Islamic State group - referred to as the so-called Islamic State - enforced extremist governance over parts of Iraq and Syria prior to its 2019 collapse.
"This strike underscores British leadership, and determination to operate in unison with our allies, to eradicate any revival of Daesh and their harmful and extremist ideologies in the region," Britain's Defence Chief John Healey stated.
British military aircraft have carried out patrols over Syria to "prevent any attempted resurgence" of IS following its routing at the battle of Baghuz in the year 2019, the MoD reported.
"I want to thank every member of our armed forces involved in this operation for their skill and their bravery," Healey said. "Including them were a great many British troops deployed over the holidays. This action, to eliminate terrorist threats who threaten our safety, shows how UK forces are always on standby, throughout the year, keeping Britain secure domestically and powerful internationally."
In December, the US military executed what it described as a "massive strike" on IS targets in the country, following an attack killed two American soldiers and a civilian linguist in Palmyra.
The United Nations reports Daesh still has between 5,000 and 7,000 combatants in Iraq and Syria.
