Royal Air Force Typhoon fighter aircraft have operated alongside French warplanes in a coordinated attack targeting an underground arms cache in Syrian territory used by the Daesh militant organization, as stated by the British defence ministry.
The location, located using reconnaissance, was believed to be housing weapons and explosive materials, the release indicated, and was located in hills just north of the historic site of Palmyra in the heart of Syria.
"Our fighter planes utilized Paveway IV guided bombs to hit a series of access tunnels down to the site... preliminary assessments suggest the objective was successfully hit," the ministry announced.
There was no indication of any civilian casualties in the strike conducted Saturday night and every plane involved returned to base without incident, the defence officials confirmed.
The Typhoon FGR4s were supported by a Voyager tanker plane.
IS - referred to as Daesh - enforced extremist governance over large swathes of Syria and Iraq until 2019.
"This operation underscores the UK's leading role, and resolve to operate in unison with allied nations, to stamp out any re-emergence of IS and their dangerous and violent ideologies in the Middle East," UK Defence Secretary the Defence Secretary said.
RAF aircraft have performed surveillance missions over Syria to "deter any attempted resurgence" of Islamic State subsequent to its defeat at the climactic battle in Baghuz in 2019, the ministry said.
"I must thank all the members of British forces who took part in this strike for their skill and their valour," Healey said. "They were part of thousands of British personnel on duty over the festive period. This action, to take out dangerous terrorists who pose a risk to our security, highlights how UK forces are ready to step up, throughout the year, ensuring Britain's security at home and influential overseas."
Last December, the American forces carried out what it termed a "major assault" on Islamic State objectives in Syria, subsequent to an assault claimed the lives of two US troops and a local interpreter in the Palmyra area.
The U.N. says IS still has between 5,000 and 7,000 combatants in both countries.
