Royal Air Force Typhoon jets have conducted a mission with French warplanes in a combined operation targeting an hidden munitions depot in Syrian territory used by the IS group, according to the UK Ministry of Defence.
The location, identified by intelligence, was assessed as storing arms and explosives, the statement said, and was situated in mountainous terrain just above the ancient city of Palmyra in the heart of Syria.
"Our fighter planes employed Paveway IV guided bombs to hit a number of access tunnels down to the facility... preliminary assessments indicate the target was engaged successfully," the MoD said.
There was no sign of any harm to civilians in the operation late on Saturday and each participating jet returned safely, the ministry further stated.
The Typhoon FGR4s were backed up by a Voyager tanker plane.
Daesh - referred to as ISIS - enforced militant control over large swathes of both Syria and Iraq until 2019.
"This action underscores British leadership, and resolve to operate in unison with our partners, to eliminate any revival of IS and their harmful and extremist ideologies in the area," UK Defence Secretary the Defence Secretary said.
British military aircraft have conducted surveillance missions over Syria to "prevent any attempted resurgence" of IS after its defeat at the Baghuz confrontation in the year 2019, the authorities noted.
"I extend gratitude to the personnel of the UK armed forces involved in this mission for their skill and their courage," Healey commented. "They were among a great many British troops on duty over Christmas and New Year. This mission, to take out dangerous terrorists who threaten our safety, demonstrates how our armed forces are prepared to act, continuously, keeping Britain secure at home and powerful internationally."
Last December, the United States armed forces executed what it called a "major assault" targeting IS targets in Syria, subsequent to an assault claimed the lives of two US servicemembers and a local interpreter in the Palmyra area.
The UN says IS still boasts between 5,000 and 7,000 combatants in both countries.
