RAF Typhoon jets have operated alongside French aircraft in a combined operation on an hidden munitions depot in Syrian territory employed by the IS group, as stated by the UK Ministry of Defence.
The facility, pinpointed through surveillance, was thought to be housing weapons and explosive materials, the statement said, and was located in mountainous terrain just above the historic site of Palmyra in central Syria.
"The RAF jets used Paveway IV guided bombs to hit a series of entry passages providing entry to the facility... initial indications indicate the target was engaged successfully," officials stated.
There was no sign of any harm to civilians in the attack late on Saturday and every plane involved returned safely, the ministry further stated.
The Typhoon fighters were assisted by a Voyager tanker plane.
IS - referred to as Daesh - established extremist governance over parts of Syria and Iraq before its territorial defeat in 2019.
"This action shows our UK leadership, and commitment to operate in unison with our allies, to eradicate any re-emergence of Daesh and their harmful and extremist ideologies in the region," Britain's Defence Chief the minister stated.
British military aircraft have carried out surveillance missions over Syrian airspace to "prevent any attempted resurgence" of IS following its military defeat at the battle of Baghuz in 2019, the ministry said.
"I want to thank the personnel of the UK armed forces who took part in this strike for their skill and their courage," the Defence Secretary commented. "They were among thousands of UK service members stationed over Christmas and New Year. This operation, to remove dangerous terrorists who pose a risk to our safety, shows how British military are ready to step up, all year round, keeping Britain secure domestically and strong abroad."
In December, the United States armed forces executed what it termed a "large-scale strike" on IS targets in the country, after an attack killed two American soldiers and a civilian interpreter in Palmyra.
The United Nations says Islamic State still boasts between 5,000 and 7,000 combatants in both countries.
