RAF Typhoon FGR4s have joined forces with French warplanes in a joint strike targeting an underground arms cache in Syria operated by the Daesh militant organization, according to the UK Ministry of Defence.
The facility, located using intelligence, was believed to be storing arms and explosives, the announcement noted, and was located in mountainous terrain just above the historic site of Palmyra in Syria's central region.
"Our fighter planes utilized precision-guided Paveway IV munitions to strike a several approach shafts providing entry to the site... initial indications are that the objective was successfully hit," the MoD said.
There was no indication of any harm to civilians in the strike on Saturday evening and every plane involved returned to base without incident, the defence officials confirmed.
The Typhoon FGR4s were backed up by a Voyager aerial refuelling aircraft.
The Islamic State group - also known as ISIS - established militant control over significant areas in both Syria and Iraq until 2019.
"This operation shows British leadership, and resolve to work closely with our allies, to stamp out any re-emergence of Daesh and their dangerous and violent ideologies in the area," Britain's Defence Chief John Healey said.
British military aircraft have carried out patrols over Syrian airspace to "deter any efforts to regroup" of Islamic State after its routing at the Baghuz confrontation in the year 2019, the authorities noted.
"I extend gratitude to the personnel of British forces participating in this mission for their skill and their courage," he added. "They were part of a great many British personnel on duty over Christmas and New Year. This operation, to take out dangerous terrorists who threaten our way of life, demonstrates how UK forces are always on standby, continuously, ensuring Britain's security at home and strong abroad."
During December, the US military carried out what it called a "massive strike" on IS targets in the country, following an assault resulted in the deaths of two American soldiers and a civilian interpreter in the Palmyra area.
The UN reports Islamic State still maintains between 5,000 and 7,000 militants in both countries.
