British Air Force Typhoon jets have operated alongside France's air force in a coordinated attack against an subterranean weapons facility in Syrian territory operated by the IS group, according to the UK's MoD.
The facility, identified by intelligence, was thought to be storing arms and explosives, the release indicated, and was situated in mountainous terrain just north of the historic site of Palmyra in central Syria.
"The RAF jets used precision-guided Paveway IV munitions to strike a number of entry passages down to the facility... early reports indicate the target was engaged successfully," officials stated.
There was no evidence of any civilian casualties in the attack conducted Saturday night and all the aircraft returned to base without incident, the ministry further stated.
The Typhoon fighters were assisted by a Voyager aerial refuelling aircraft.
Daesh - referred to as ISIS - imposed jihadist rule over significant areas in Iraq and Syria prior to its 2019 collapse.
"This action underscores the UK's leading role, and commitment to stand shoulder to shoulder with allied nations, to stamp out any re-emergence of IS and their dangerous and violent ideologies in the region," Britain's Defence Chief the minister said.
UK warplanes have conducted surveillance missions over Syria to "forestall any attempted resurgence" of Islamic State subsequent to its routing at the climactic battle in Baghuz in 2019, the MoD reported.
"I must thank every member of our armed forces participating in this mission for their professionalism and their courage," Healey said. "They were among numerous UK service members deployed over the festive period. This operation, to take out terrorist threats who endanger our way of life, highlights how our armed forces are ready to step up, all year round, keeping Britain secure domestically and influential overseas."
During December, the US military executed what it described as a "major assault" targeting IS targets in the country, following an ambush killed two American soldiers and a local interpreter in the Palmyra area.
The United Nations says Islamic State still has roughly 5-7 thousand fighters in Syria and Iraq.
