Royal Air Force Typhoon FGR4s have conducted a mission with French warplanes in a joint strike targeting an subterranean weapons facility in Syria operated by the Islamic State group (IS), as stated by the UK Ministry of Defence.
The facility, identified by intelligence, was assessed as containing munitions and bombs, the statement said, and was situated in mountains just north of the historic site of Palmyra in central Syria.
"Our fighter planes employed laser-guided Paveway IV weapons to hit a several access tunnels down to the facility... early reports suggest the target was engaged successfully," the MoD said.
There was no evidence of any harm to civilians in the attack late on Saturday and every plane involved returned to base without incident, the ministry further stated.
The Typhoon FGR4s were assisted by a Voyager tanker plane.
Daesh - alternatively referred to as the so-called Islamic State - enforced extremist governance over significant areas in Syria and Iraq until 2019.
"This strike underscores British leadership, and determination to stand shoulder to shoulder with our allies, to eradicate any revival of the terrorist group and their harmful and extremist ideologies in the area," Britain's Defence Chief the minister said.
RAF aircraft have conducted patrols over Syria to "deter any attempted comeback" of the group after its military defeat at the Baghuz confrontation in 2019, the authorities noted.
"I extend gratitude to all the members of our armed forces participating in this mission for their expertise and their courage," Healey said. "They were part of a great many British troops deployed over the holidays. This mission, to take out dangerous terrorists who pose a risk to our safety, shows how British military are ready to step up, all year round, protecting the UK domestically and influential overseas."
Last December, the American forces carried out what it called a "major assault" targeting Daesh sites in the country, subsequent to an ambush claimed the lives of two US servicemembers and a local interpreter in the Palmyra area.
The UN reports Daesh still boasts between 5,000 and 7,000 combatants in Iraq and Syria.
