British Air Force Typhoon fighter aircraft have conducted a mission with France's air force in a coordinated attack on an hidden munitions depot in Syrian territory used by the Islamic State group (IS), as stated by the British defence ministry.
The site, located using surveillance, was believed to be containing munitions and bombs, the statement said, and was positioned in mountains just to the north of Palmyra in Syria's central region.
"The RAF jets employed precision-guided Paveway IV munitions to strike a several access tunnels down to the site... early reports indicate the strike was effective," the ministry announced.
There was no sign of any civilian casualties in the attack conducted Saturday night and every plane involved returned safely, the MoD added.
The Typhoon FGR4s were assisted by a Voyager refuelling tanker.
Daesh - also known as ISIS - enforced extremist governance over parts of both Syria and Iraq before its territorial defeat in 2019.
"This strike demonstrates our UK leadership, and resolve to stand shoulder to shoulder with allied nations, to stamp out any revival of the terrorist group and their dangerous and violent ideologies in the area," the British Defence Secretary John Healey stated.
RAF aircraft have carried out patrols over Syrian airspace to "deter any attempted comeback" of the group subsequent to its defeat at the Baghuz confrontation in 2019, the authorities noted.
"I extend gratitude to every member of our armed forces who took part in this operation for their professionalism and their valour," the Defence Secretary added. "They were among thousands of British troops on duty over the holidays. This mission, to take out terrorist threats who pose a risk to our security, shows how UK forces are prepared to act, throughout the year, keeping Britain secure domestically and strong abroad."
Last December, the American forces carried out what it called a "massive strike" on Islamic State objectives in Syria, subsequent to an assault claimed the lives of two US servicemembers and a civilian interpreter in Palmyra.
The U.N. estimates Daesh still has an estimated 5,000 to 7,000 combatants in both countries.
