Royal Air Force Typhoon FGR4s have operated alongside French warplanes in a coordinated attack against an subterranean weapons facility in Syria employed by the Islamic State group (IS), per a report from the UK Ministry of Defence.
The site, identified by surveillance, was thought to be storing arms and explosives, the release indicated, and was situated in mountains just above the historic site of Palmyra in the heart of Syria.
"Our aircraft employed precision-guided Paveway IV munitions to hit a series of approach shafts down to the site... initial indications are that the objective was successfully hit," the MoD said.
There was no evidence of any civilian casualties in the operation late on Saturday and every plane involved made a safe return, the MoD added.
The Typhoon FGR4s were backed up by a Voyager refuelling tanker.
The Islamic State group - referred to as ISIS - established jihadist rule over significant areas in Syria and Iraq before its territorial defeat in 2019.
"This operation shows the UK's leading role, and determination to stand shoulder to shoulder with our allies, to eliminate any resurgence of IS and their harmful and extremist ideologies in the region," UK Defence Secretary the minister remarked.
UK warplanes have performed overwatch operations over Syrian airspace to "forestall any attempted resurgence" of the group after its routing at the battle of Baghuz in 2019, the authorities noted.
"I must thank the personnel of our armed forces participating in this mission for their skill and their valour," Healey commented. "They were among thousands of British troops stationed over the holidays. This operation, to take out dangerous terrorists who pose a risk to our security, demonstrates how our armed forces are always on standby, throughout the year, ensuring Britain's security at home and powerful internationally."
In December, the United States armed forces conducted what it termed a "large-scale strike" against IS targets in the country, subsequent to an attack claimed the lives of two US troops and a civilian interpreter in the Palmyra area.
The UN estimates Islamic State still boasts an estimated 5,000 to 7,000 fighters in both countries.
