Royal Air Force Typhoon fighter aircraft have conducted a mission with France's air force in a combined operation against an hidden munitions depot in Syrian territory employed by the Daesh militant organization, as stated by the UK's MoD.
The location, located using reconnaissance, was assessed as storing arms and explosives, the announcement noted, and was situated in mountainous terrain just above the historic site of Palmyra in Syria's central region.
"The RAF jets employed Paveway IV guided bombs to target a series of approach shafts providing entry to the facility... early reports indicate the target was engaged successfully," the MoD said.
There was no sign of any civilian casualties in the strike conducted Saturday night and every plane involved returned to base without incident, the defence officials confirmed.
The British jets were backed up by a Voyager aerial refuelling aircraft.
Daesh - referred to as Daesh - established jihadist rule over parts of Syria and Iraq before its territorial defeat in 2019.
"This operation demonstrates British leadership, and determination to work closely with our allies, to stamp out any re-emergence of Daesh and their violent and radical beliefs in the area," UK Defence Secretary the Defence Secretary remarked.
RAF aircraft have conducted patrols over Syria to "forestall any attempted resurgence" of Islamic State after its defeat at the Baghuz confrontation in 2019, the MoD reported.
"I extend gratitude to every member of the UK armed forces involved in this mission for their expertise and their courage," he added. "Including them were a great many UK service members deployed over Christmas and New Year. This action, to take out dangerous terrorists who pose a risk to our security, highlights how our armed forces are always on standby, all year round, protecting the UK within its borders and strong abroad."
During December, the American forces carried out what it termed a "major assault" against Islamic State objectives in Syria, after an assault claimed the lives of two US troops and a civilian linguist in Palmyra.
The U.N. says Islamic State still has between 5,000 and 7,000 militants in both countries.
