Royal Air Force Typhoon fighter aircraft have joined forces with French aircraft in a coordinated attack against an hidden munitions depot in Syrian territory used by the Islamic State group (IS), as stated by the British defence ministry.
The site, identified by surveillance, was believed to be housing weapons and explosive materials, the release indicated, and was situated in mountainous terrain just to the north of Palmyra in Syria's central region.
"The RAF jets used laser-guided Paveway IV weapons to strike a series of approach shafts providing entry to the depot... preliminary assessments suggest the objective was successfully hit," the MoD said.
There was no sign of any civilian casualties in the attack late on Saturday and all the aircraft returned safely, the ministry further stated.
The British jets were backed up by a Voyager tanker plane.
IS - also known as the so-called Islamic State - enforced militant control over parts of Syria and Iraq prior to its 2019 collapse.
"This action underscores the UK's leading role, and commitment to work closely with our partners, to stamp out any revival of IS and their dangerous and violent ideologies in the Middle East," the British Defence Secretary the Defence Secretary remarked.
RAF aircraft have conducted overwatch operations over Syrian airspace to "deter any efforts to regroup" of IS after its military defeat at the climactic battle in Baghuz in 2019, the ministry said.
"I want to thank all the members of our armed forces who took part in this operation for their skill and their valour," Healey added. "They were among a great many British troops deployed over the festive period. This mission, to eliminate terrorist threats who pose a risk to our safety, highlights how UK forces are prepared to act, all year round, keeping Britain secure at home and influential overseas."
Last December, the American forces executed what it described as a "large-scale strike" against IS targets in Syria, subsequent to an assault resulted in the deaths of two US servicemembers and a local interpreter in Palmyra.
The United Nations estimates IS still has an estimated 5,000 to 7,000 fighters in Iraq and Syria.
