British Air Force Typhoon fighter aircraft have operated alongside French warplanes in a joint strike against an subterranean weapons facility in Syrian territory used by the IS group, as stated by the UK's MoD.
The facility, pinpointed through surveillance, was believed to be housing weapons and explosive materials, the statement said, and was situated in hills just north of the historic site of Palmyra in central Syria.
"Our aircraft employed laser-guided Paveway IV weapons to strike a several access tunnels down to the site... preliminary assessments indicate the target was engaged successfully," the MoD said.
There was no sign of any civilian impact in the operation on Saturday evening and every plane involved returned safely, the defence officials confirmed.
The Typhoon FGR4s were assisted by a Voyager tanker plane.
Daesh - referred to as Daesh - established extremist governance over large swathes of Iraq and Syria before its territorial defeat in 2019.
"This operation underscores the UK's leading role, and determination to work closely with our allies, to eradicate any re-emergence of Daesh and their violent and radical beliefs in the region," Britain's Defence Chief the minister said.
British military aircraft have carried out patrols over Syrian airspace to "prevent any efforts to regroup" of IS subsequent to its defeat at the battle of Baghuz in the year 2019, the ministry said.
"I must thank every member of British forces involved in this operation for their skill and their courage," Healey added. "They were part of numerous British troops deployed over the festive period. This operation, to remove terrorist threats who pose a risk to our security, highlights how British military are always on standby, all year round, keeping Britain secure at home and powerful internationally."
During December, the US military conducted what it termed a "large-scale strike" targeting Daesh sites in Syria, after an ambush killed two American soldiers and a local interpreter in Palmyra.
The United Nations says Islamic State still has roughly 5-7 thousand fighters in both countries.
