British Air Force Typhoon FGR4s have operated alongside France's air force in a combined operation on an hidden munitions depot in Syria used by the Daesh militant organization, as stated by the UK's MoD.
The site, identified by surveillance, was assessed as storing arms and explosives, the release indicated, and was situated in mountainous terrain just above the historic site of Palmyra in Syria's central region.
"Our fighter planes utilized laser-guided Paveway IV weapons to target a number of access tunnels down to the facility... preliminary assessments are that the target was engaged successfully," officials stated.
There was no indication of any harm to civilians in the attack conducted Saturday night and each participating jet made a safe return, the MoD added.
The Typhoon FGR4s were supported by a Voyager tanker plane.
IS - referred to as the so-called Islamic State - imposed jihadist rule over significant areas in Iraq and Syria until 2019.
"This strike demonstrates the UK's leading role, and commitment to operate in unison with our partners, to stamp out any revival of the terrorist group and their violent and radical beliefs in the area," Britain's Defence Chief the minister said.
British military aircraft have conducted patrols over Syrian airspace to "deter any attempted comeback" of IS after its military defeat at the battle of Baghuz in 2019, the ministry said.
"I want to thank the personnel of British forces involved in this operation for their expertise and their valour," the Defence Secretary said. "Including them were thousands of UK service members deployed over Christmas and New Year. This action, to eliminate terrorist threats who threaten our security, highlights how British military are always on standby, all year round, protecting the UK domestically and powerful internationally."
In December, the United States armed forces executed what it called a "large-scale strike" on IS targets in Syria, after an attack resulted in the deaths of two US troops and a local interpreter in Palmyra.
The U.N. says Daesh still boasts roughly 5-7 thousand fighters in Syria and Iraq.
