RAF Typhoon FGR4s have operated alongside French warplanes in a coordinated attack on an subterranean weapons facility in Syrian territory operated by the IS group, according to the UK Ministry of Defence.
The site, identified by surveillance, was believed to be housing weapons and explosive materials, the announcement noted, and was located in mountainous terrain just to the north of the historic site of Palmyra in central Syria.
"The RAF jets utilized laser-guided Paveway IV weapons to hit a series of approach shafts providing entry to the depot... early reports are that the target was engaged successfully," the ministry announced.
There was no evidence of any civilian casualties in the attack late on Saturday and every plane involved made a safe return, the ministry further stated.
The Typhoon fighters were assisted by a Voyager tanker plane.
Daesh - referred to as Daesh - imposed extremist governance over parts of Iraq and Syria until 2019.
"This strike underscores our UK leadership, and determination to stand shoulder to shoulder with allied nations, to eliminate any re-emergence of Daesh and their harmful and extremist ideologies in the area," Britain's Defence Chief John Healey stated.
RAF aircraft have conducted patrols over Syria to "deter any attempted comeback" of Islamic State subsequent to its defeat at the Baghuz confrontation in the year 2019, the ministry said.
"I extend gratitude to all the members of our armed forces who took part in this strike for their professionalism and their valour," he said. "They were among thousands of UK service members stationed over the holidays. This action, to remove dangerous terrorists who pose a risk to our way of life, highlights how our armed forces are prepared to act, continuously, protecting the UK at home and strong abroad."
In December, the American forces executed what it termed a "massive strike" on Islamic State objectives in Syria, subsequent to an ambush claimed the lives of two US troops and a local interpreter in Palmyra.
The United Nations estimates Daesh still boasts roughly 5-7 thousand combatants in Syria and Iraq.
