British Air Force Typhoon fighter aircraft have joined forces with French aircraft in a coordinated attack on an underground arms cache in Syria employed by the IS group, per a report from the British defence ministry.
The location, identified by reconnaissance, was assessed as containing munitions and bombs, the release indicated, and was located in mountains just to the north of the historic site of Palmyra in Syria's central region.
"Our aircraft employed laser-guided Paveway IV weapons to hit a series of access tunnels providing entry to the site... early reports suggest the target was engaged successfully," the ministry announced.
There was no sign of any civilian casualties in the operation conducted Saturday night and all the aircraft returned safely, the MoD added.
The British jets were assisted by a Voyager aerial refuelling aircraft.
The Islamic State group - alternatively referred to as the so-called Islamic State - imposed extremist governance over parts of Syria and Iraq until 2019.
"This strike demonstrates British leadership, and resolve to stand shoulder to shoulder with allied nations, to eliminate any revival of Daesh and their harmful and extremist ideologies in the area," UK Defence Secretary the minister stated.
UK warplanes have carried out surveillance missions over Syria to "forestall any efforts to regroup" of IS after its defeat at the Baghuz confrontation in 2019, the authorities noted.
"I must thank every member of British forces who took part in this operation for their expertise and their valour," he commented. "They were among a great many UK service members on duty over Christmas and New Year. This mission, to remove terrorist threats who endanger our security, highlights how British military are prepared to act, continuously, ensuring Britain's security within its borders and powerful internationally."
During December, the United States armed forces conducted what it called a "massive strike" against IS targets in Syria, subsequent to an ambush resulted in the deaths of two US troops and a civilian linguist in Palmyra.
The U.N. estimates Daesh still maintains between 5,000 and 7,000 fighters in Syria and Iraq.
