British Air Force Typhoon FGR4s have operated alongside France's air force in a joint strike targeting an hidden munitions depot in Syria operated by the Islamic State group (IS), according to the British defence ministry.
The site, identified by surveillance, was thought to be storing arms and explosives, the release indicated, and was positioned in mountains just above the ancient city of Palmyra in Syria's central region.
"Our aircraft used Paveway IV guided bombs to strike a number of entry passages leading to the site... preliminary assessments indicate the objective was successfully hit," officials stated.
There was no sign of any civilian casualties in the strike on Saturday evening and all the aircraft returned safely, the MoD added.
The British jets were assisted by a Voyager aerial refuelling aircraft.
Daesh - also known as ISIS - enforced jihadist rule over significant areas in both Syria and Iraq before its territorial defeat in 2019.
"This action underscores our UK leadership, and commitment to operate in unison with our allies, to stamp out any resurgence of the terrorist group and their dangerous and violent ideologies in the area," UK Defence Secretary the minister remarked.
RAF aircraft have performed overwatch operations over Syrian airspace to "prevent any efforts to regroup" of Islamic State following its military defeat at the climactic battle in Baghuz in 2019, the MoD reported.
"I must thank all the members of the UK armed forces who took part in this operation for their skill and their bravery," the Defence Secretary commented. "They were part of thousands of UK service members on duty over Christmas and New Year. This operation, to eliminate terrorist threats who endanger our safety, highlights how British military are always on standby, throughout the year, ensuring Britain's security domestically and powerful internationally."
Last December, the United States armed forces carried out what it described as a "large-scale strike" against Daesh sites in the country, subsequent to an ambush claimed the lives of two American soldiers and a civilian linguist in the Palmyra area.
The UN says Daesh still maintains an estimated 5,000 to 7,000 fighters in both countries.
