British Air Force Typhoon FGR4s have joined forces with France's air force in a combined operation against an subterranean weapons facility in Syria operated by the Islamic State group (IS), according to the British defence ministry.
The location, located using intelligence, was assessed as containing munitions and bombs, the statement said, and was situated in mountainous terrain just to the north of Palmyra in Syria's central region.
"Our fighter planes used Paveway IV guided bombs to target a series of approach shafts leading to the site... preliminary assessments are that the objective was successfully hit," the ministry announced.
There was no evidence of any harm to civilians in the attack late on Saturday and all the aircraft returned to base without incident, the ministry further stated.
The British jets were backed up by a Voyager aerial refuelling aircraft.
The Islamic State group - referred to as Daesh - imposed jihadist rule over significant areas in Iraq and Syria before its territorial defeat in 2019.
"This strike underscores British leadership, and commitment to stand shoulder to shoulder with allied nations, to eradicate any revival of the terrorist group and their dangerous and violent ideologies in the area," UK Defence Secretary the minister remarked.
British military aircraft have carried out overwatch operations over Syria to "deter any efforts to regroup" of IS following its routing at the Baghuz confrontation in 2019, the MoD reported.
"I extend gratitude to all the members of our armed forces participating in this operation for their skill and their courage," he said. "They were among a great many British personnel on duty over the holidays. This operation, to take out terrorist threats who threaten our way of life, shows how British military are ready to step up, all year round, keeping Britain secure domestically and powerful internationally."
In December, the United States armed forces conducted what it termed a "major assault" on Daesh sites in the country, subsequent to an attack killed two American soldiers and a civilian linguist in the Palmyra area.
The United Nations estimates Daesh still has an estimated 5,000 to 7,000 militants in both countries.
