British Air Force Typhoon FGR4s have operated alongside France's air force in a joint strike on an underground arms cache in Syria employed by the Islamic State group (IS), per a report from the British defence ministry.
The location, pinpointed through reconnaissance, was assessed as containing munitions and bombs, the release indicated, and was positioned in mountainous terrain just north of the ancient city of Palmyra in central Syria.
"Our aircraft used laser-guided Paveway IV weapons to strike a series of entry passages leading to the depot... preliminary assessments are that the target was engaged successfully," the MoD said.
There was no evidence of any civilian casualties in the strike on Saturday evening and every plane involved returned to base without incident, the ministry further stated.
The British jets were supported by a Voyager aerial refuelling aircraft.
IS - also known as Daesh - imposed militant control over parts of Iraq and Syria before its territorial defeat in 2019.
"This operation demonstrates the UK's leading role, and resolve to stand shoulder to shoulder with allied nations, to eradicate any resurgence of the terrorist group and their harmful and extremist ideologies in the area," UK Defence Secretary John Healey said.
UK warplanes have performed patrols over Syria to "prevent any attempted resurgence" of IS subsequent to its military defeat at the climactic battle in Baghuz in 2019, the authorities noted.
"I must thank every member of our armed forces who took part in this strike for their expertise and their valour," he added. "They were among numerous British personnel stationed over the festive period. This action, to eliminate dangerous terrorists who endanger our safety, shows how our armed forces are ready to step up, continuously, keeping Britain secure within its borders and influential overseas."
Last December, the US military executed what it described as a "major assault" on Daesh sites in the country, subsequent to an attack resulted in the deaths of two American soldiers and a civilian linguist in the Palmyra area.
The UN estimates Islamic State still has an estimated 5,000 to 7,000 fighters in Iraq and Syria.
