British Air Force Typhoon fighter aircraft have operated alongside French aircraft in a combined operation targeting an underground arms cache in Syria operated by the Daesh militant organization, as stated by the British defence ministry.
The facility, pinpointed through reconnaissance, was assessed as containing munitions and bombs, the statement said, and was situated in mountains just above the ancient city of Palmyra in Syria's central region.
"Our aircraft used Paveway IV guided bombs to strike a series of entry passages down to the site... early reports indicate the strike was effective," the ministry announced.
There was no sign of any harm to civilians in the operation on Saturday evening and each participating jet returned safely, the defence officials confirmed.
The British jets were supported by a Voyager aerial refuelling aircraft.
IS - alternatively referred to as ISIS - established extremist governance over significant areas in both Syria and Iraq before its territorial defeat in 2019.
"This operation demonstrates British leadership, and determination to stand shoulder to shoulder with allied nations, to stamp out any resurgence of the terrorist group and their violent and radical beliefs in the region," Britain's Defence Chief John Healey stated.
UK warplanes have performed patrols over Syria to "prevent any efforts to regroup" of the group following its routing at the Baghuz confrontation in the year 2019, the ministry said.
"I want to thank all the members of British forces involved in this mission for their professionalism and their valour," he said. "They were among a great many British personnel deployed over Christmas and New Year. This action, to remove militants who threaten our way of life, demonstrates how our armed forces are prepared to act, all year round, protecting the UK within its borders and strong abroad."
In December, the American forces executed what it termed a "large-scale strike" against Islamic State objectives in Syria, following an ambush resulted in the deaths of two American soldiers and a civilian linguist in the Palmyra area.
The UN reports Daesh still boasts roughly 5-7 thousand combatants in both countries.
