RAF Typhoon FGR4s have conducted a mission with France's air force in a coordinated attack on an hidden munitions depot in Syria used by the Daesh militant organization, as stated by the UK Ministry of Defence.
The site, identified by surveillance, was thought to be storing arms and explosives, the statement said, and was located in mountains just above Palmyra in Syria's central region.
"Our fighter planes used laser-guided Paveway IV weapons to hit a number of approach shafts down to the facility... preliminary assessments are that the target was engaged successfully," the ministry announced.
There was no sign of any harm to civilians in the attack on Saturday evening and all the aircraft returned safely, the defence officials confirmed.
The Typhoon fighters were assisted by a Voyager refuelling tanker.
Daesh - also known as Daesh - imposed militant control over large swathes of both Syria and Iraq until 2019.
"This action shows British leadership, and commitment to operate in unison with allied nations, to eliminate any resurgence of the terrorist group and their dangerous and violent ideologies in the area," UK Defence Secretary John Healey stated.
British military aircraft have performed overwatch operations over Syrian airspace to "forestall any efforts to regroup" of Islamic State following its routing at the climactic battle in Baghuz in 2019, the authorities noted.
"I want to thank the personnel of British forces participating in this mission for their professionalism and their bravery," the Defence Secretary said. "They were part of a great many UK service members deployed over the festive period. This mission, to eliminate militants who endanger our security, demonstrates how our armed forces are prepared to act, all year round, protecting the UK at home and powerful internationally."
Last December, the United States armed forces carried out what it termed a "major assault" on Islamic State objectives in Syria, subsequent to an ambush killed two American soldiers and a civilian interpreter in the Palmyra area.
The United Nations reports Islamic State still has an estimated 5,000 to 7,000 fighters in Syria and Iraq.
