RAF Typhoon jets have operated alongside France's air force in a coordinated attack on an hidden munitions depot in Syria employed by the Daesh militant organization, as stated by the UK Ministry of Defence.
The site, identified by reconnaissance, was thought to be containing munitions and bombs, the statement said, and was positioned in mountains just above Palmyra in the heart of Syria.
"Our aircraft used laser-guided Paveway IV weapons to hit a several access tunnels providing entry to the facility... preliminary assessments indicate the objective was successfully hit," the ministry announced.
There was no indication of any harm to civilians in the attack late on Saturday and each participating jet returned to base without incident, the MoD added.
The Typhoon FGR4s were supported by a Voyager tanker plane.
Daesh - referred to as ISIS - enforced jihadist rule over large swathes of Syria and Iraq until 2019.
"This action shows the UK's leading role, and resolve to operate in unison with our allies, to stamp out any resurgence of IS and their violent and radical beliefs in the Middle East," the British Defence Secretary the minister said.
UK warplanes have conducted patrols over Syrian airspace to "forestall any attempted resurgence" of the group subsequent to its military defeat at the battle of Baghuz in the year 2019, the MoD reported.
"I want to thank all the members of the UK armed forces involved in this mission for their expertise and their valour," Healey said. "They were among thousands of British personnel on duty over the holidays. This mission, to take out dangerous terrorists who threaten our safety, demonstrates how British military are prepared to act, all year round, protecting the UK within its borders and strong abroad."
In December, the US military carried out what it called a "large-scale strike" on Daesh sites in Syria, subsequent to an ambush resulted in the deaths of two US servicemembers and a civilian interpreter in Palmyra.
The U.N. reports IS still maintains between 5,000 and 7,000 fighters in Syria and Iraq.
