RAF Typhoon jets have conducted a mission with French warplanes in a coordinated attack targeting an hidden munitions depot in Syrian territory operated by the IS group, according to the UK Ministry of Defence.
The facility, located using surveillance, was thought to be housing weapons and explosive materials, the statement said, and was situated in mountainous terrain just to the north of Palmyra in central Syria.
"Our fighter planes utilized Paveway IV guided bombs to hit a number of entry passages down to the depot... early reports indicate the objective was successfully hit," the MoD said.
There was no evidence of any harm to civilians in the strike late on Saturday and every plane involved returned safely, the ministry further stated.
The British jets were supported by a Voyager aerial refuelling aircraft.
Daesh - referred to as ISIS - enforced jihadist rule over parts of Syria and Iraq prior to its 2019 collapse.
"This operation underscores British leadership, and determination to operate in unison with allied nations, to eradicate any revival of IS and their violent and radical beliefs in the region," the British Defence Secretary the Defence Secretary stated.
UK warplanes have performed overwatch operations over Syrian airspace to "forestall any attempted resurgence" of IS following its routing at the climactic battle in Baghuz in 2019, the authorities noted.
"I must thank every member of the UK armed forces involved in this mission for their expertise and their valour," Healey added. "They were among a great many British troops on duty over the holidays. This action, to eliminate dangerous terrorists who pose a risk to our security, highlights how UK forces are always on standby, continuously, keeping Britain secure within its borders and powerful internationally."
