Royal Air Force Typhoon FGR4s have joined forces with France's air force in a combined operation on an subterranean weapons facility in Syrian territory employed by the Islamic State group (IS), according to the UK Ministry of Defence.
The site, identified by reconnaissance, was assessed as housing weapons and explosive materials, the statement said, and was located in mountains just to the north of the ancient city of Palmyra in the heart of Syria.
"Our aircraft employed Paveway IV guided bombs to hit a several access tunnels leading to the site... initial indications are that the strike was effective," the ministry announced.
There was no sign of any civilian impact in the attack on Saturday evening and each participating jet returned to base without incident, the ministry further stated.
The Typhoon FGR4s were backed up by a Voyager refuelling tanker.
Daesh - also known as ISIS - imposed jihadist rule over parts of Syria and Iraq prior to its 2019 collapse.
"This action underscores our UK leadership, and determination to work closely with our allies, to stamp out any revival of Daesh and their dangerous and violent ideologies in the area," Britain's Defence Chief the minister said.
RAF aircraft have carried out patrols over Syrian airspace to "forestall any attempted resurgence" of the group after its defeat at the climactic battle in Baghuz in 2019, the MoD reported.
"I want to thank all the members of British forces participating in this operation for their expertise and their bravery," Healey commented. "Including them were thousands of British troops deployed over the festive period. This mission, to take out dangerous terrorists who endanger our safety, highlights how British military are prepared to act, continuously, protecting the UK at home and strong abroad."
Last December, the US military executed what it described as a "large-scale strike" on Islamic State objectives in Syria, following an ambush claimed the lives of two US troops and a civilian linguist in the Palmyra area.
The UN says Daesh still boasts between 5,000 and 7,000 militants in Syria and Iraq.
