British Air Force Typhoon fighter aircraft have operated alongside France's air force in a coordinated attack on an subterranean weapons facility in Syria employed by the Daesh militant organization, as stated by the British defence ministry.
The facility, identified by intelligence, was thought to be housing weapons and explosive materials, the statement said, and was located in mountains just north of Palmyra in the heart of Syria.
"The RAF jets employed Paveway IV guided bombs to hit a number of access tunnels leading to the depot... initial indications suggest the target was engaged successfully," the ministry announced.
There was no evidence of any harm to civilians in the strike late on Saturday and all the aircraft made a safe return, the MoD added.
The British jets were assisted by a Voyager tanker plane.
IS - also known as ISIS - enforced militant control over parts of both Syria and Iraq prior to its 2019 collapse.
"This operation underscores British leadership, and determination to operate in unison with our partners, to eliminate any re-emergence of IS and their harmful and extremist ideologies in the region," Britain's Defence Chief John Healey said.
British military aircraft have carried out patrols over Syrian airspace to "forestall any efforts to regroup" of IS following its defeat at the Baghuz confrontation in 2019, the authorities noted.
"I must thank every member of British forces participating in this mission for their skill and their bravery," the Defence Secretary said. "They were among thousands of UK service members on duty over the holidays. This mission, to take out terrorist threats who pose a risk to our safety, demonstrates how British military are always on standby, all year round, protecting the UK at home and powerful internationally."
In December, the United States armed forces carried out what it described as a "massive strike" against IS targets in the country, following an assault claimed the lives of two US servicemembers and a civilian interpreter in Palmyra.
The United Nations estimates Daesh still maintains an estimated 5,000 to 7,000 fighters in both countries.
