British Air Force Typhoon fighter aircraft have joined forces with French aircraft in a joint strike on an underground arms cache in Syrian territory employed by the IS group, as stated by the UK's MoD.
The site, pinpointed through surveillance, was thought to be housing weapons and explosive materials, the announcement noted, and was situated in mountainous terrain just north of Palmyra in the heart of Syria.
"Our fighter planes employed Paveway IV guided bombs to target a several access tunnels providing entry to the site... early reports indicate the strike was effective," the ministry announced.
There was no evidence of any harm to civilians in the operation on Saturday evening and all the aircraft returned safely, the defence officials confirmed.
The British jets were backed up by a Voyager tanker plane.
The Islamic State group - also known as ISIS - enforced militant control over significant areas in Iraq and Syria prior to its 2019 collapse.
"This action demonstrates the UK's leading role, and commitment to operate in unison with our allies, to stamp out any re-emergence of IS and their harmful and extremist ideologies in the region," Britain's Defence Chief the Defence Secretary said.
British military aircraft have conducted patrols over Syrian airspace to "deter any efforts to regroup" of the group subsequent to its routing at the climactic battle in Baghuz in 2019, the authorities noted.
"I want to thank every member of the UK armed forces who took part in this operation for their skill and their valour," he added. "They were among numerous British personnel on duty over the festive period. This mission, to remove militants who pose a risk to our way of life, demonstrates how our armed forces are prepared to act, continuously, ensuring Britain's security domestically and strong abroad."
In December, the American forces carried out what it termed a "major assault" against Daesh sites in the country, subsequent to an ambush claimed the lives of two American soldiers and a local interpreter in Palmyra.
The U.N. estimates Daesh still boasts roughly 5-7 thousand fighters in Syria and Iraq.
