Royal Air Force Typhoon fighter aircraft have conducted a mission with France's air force in a combined operation targeting an hidden munitions depot in Syria used by the Daesh militant organization, as stated by the UK Ministry of Defence.
The facility, located using reconnaissance, was thought to be housing weapons and explosive materials, the release indicated, and was located in mountains just above the ancient city of Palmyra in central Syria.
"Our fighter planes employed laser-guided Paveway IV weapons to hit a series of entry passages down to the facility... initial indications are that the objective was successfully hit," officials stated.
There was no indication of any harm to civilians in the attack late on Saturday and all the aircraft returned to base without incident, the defence officials confirmed.
The Typhoon fighters were backed up by a Voyager tanker plane.
The Islamic State group - also known as ISIS - established militant control over large swathes of both Syria and Iraq prior to its 2019 collapse.
"This operation shows the UK's leading role, and determination to work closely with our partners, to eliminate any resurgence of Daesh and their dangerous and violent ideologies in the region," the British Defence Secretary John Healey remarked.
RAF aircraft have carried out surveillance missions over Syrian airspace to "forestall any attempted resurgence" of Islamic State after its military defeat at the climactic battle in Baghuz in 2019, the MoD reported.
"I must thank all the members of our armed forces who took part in this operation for their expertise and their courage," Healey added. "Including them were a great many British troops deployed over Christmas and New Year. This operation, to eliminate terrorist threats who pose a risk to our security, demonstrates how UK forces are always on standby, all year round, keeping Britain secure within its borders and powerful internationally."
Last December, the United States armed forces executed what it called a "large-scale strike" targeting IS targets in the country, after an ambush killed two American soldiers and a civilian linguist in Palmyra.
The United Nations reports IS still boasts roughly 5-7 thousand militants in Iraq and Syria.
