British Air Force Typhoon FGR4s have conducted a mission with France's air force in a coordinated attack on an underground arms cache in Syria employed by the IS group, as stated by the UK Ministry of Defence.
The facility, identified by intelligence, was assessed as containing munitions and bombs, the release indicated, and was situated in hills just above the ancient city of Palmyra in the heart of Syria.
"The RAF jets employed Paveway IV guided bombs to hit a series of access tunnels providing entry to the facility... initial indications suggest the target was engaged successfully," officials stated.
There was no sign of any civilian impact in the operation late on Saturday and every plane involved returned safely, the defence officials confirmed.
The British jets were assisted by a Voyager refuelling tanker.
Daesh - also known as Daesh - imposed extremist governance over significant areas in Syria and Iraq before its territorial defeat in 2019.
"This strike shows the UK's leading role, and determination to work closely with allied nations, to stamp out any resurgence of Daesh and their violent and radical beliefs in the region," the British Defence Secretary John Healey stated.
UK warplanes have performed surveillance missions over Syria to "forestall any efforts to regroup" of IS after its defeat at the battle of Baghuz in 2019, the ministry said.
"I want to thank the personnel of British forces participating in this strike for their skill and their valour," he said. "They were among numerous British troops deployed over Christmas and New Year. This operation, to remove dangerous terrorists who pose a risk to our security, demonstrates how UK forces are prepared to act, continuously, ensuring Britain's security within its borders and powerful internationally."
During December, the American forces executed what it described as a "massive strike" against Daesh sites in Syria, following an assault resulted in the deaths of two American soldiers and a local interpreter in the Palmyra area.
The United Nations estimates Islamic State still has roughly 5-7 thousand militants in both countries.
