RAF Typhoon FGR4s have operated alongside French warplanes in a coordinated attack targeting an hidden munitions depot in Syria operated by the Islamic State group (IS), per a report from the UK's MoD.
The facility, identified by reconnaissance, was thought to be storing arms and explosives, the release indicated, and was positioned in mountainous terrain just to the north of Palmyra in the heart of Syria.
"The RAF jets used laser-guided Paveway IV weapons to hit a number of access tunnels down to the facility... initial indications suggest the strike was effective," the MoD said.
There was no sign of any civilian casualties in the operation on Saturday evening and each participating jet returned to base without incident, the defence officials confirmed.
The Typhoon FGR4s were supported by a Voyager refuelling tanker.
Daesh - alternatively referred to as the so-called Islamic State - established jihadist rule over large swathes of Syria and Iraq prior to its 2019 collapse.
"This strike underscores British leadership, and resolve to work closely with allied nations, to eliminate any re-emergence of IS and their harmful and extremist ideologies in the area," Britain's Defence Chief the Defence Secretary said.
RAF aircraft have performed surveillance missions over Syrian airspace to "prevent any attempted comeback" of Islamic State 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 operation for their professionalism and their bravery," the Defence Secretary added. "Including them were a great many UK service members stationed over the holidays. This action, to take out militants who threaten our safety, shows how our armed forces are ready to step up, throughout the year, keeping Britain secure within its borders and powerful internationally."
During December, the United States armed forces carried out what it called a "massive strike" targeting Islamic State objectives in the country, subsequent to an attack killed two US troops and a civilian linguist in Palmyra.
The UN says Islamic State still maintains roughly 5-7 thousand militants in Iraq and Syria.
