RAF Typhoon jets have operated alongside France's air force in a coordinated attack on an subterranean weapons facility in Syrian territory employed by the Daesh militant organization, as stated by the UK Ministry of Defence.
The facility, pinpointed through surveillance, was thought to be housing weapons and explosive materials, the announcement noted, and was located in hills just north of Palmyra in the heart of Syria.
"The RAF jets utilized precision-guided Paveway IV munitions to strike a several approach shafts down to the facility... early reports suggest the objective was successfully hit," the ministry announced.
There was no evidence of any civilian casualties in the operation on Saturday evening and all the aircraft returned to base without incident, the defence officials confirmed.
The Typhoon FGR4s were assisted by a Voyager tanker plane.
IS - also known as Daesh - established jihadist rule over large swathes of Iraq and Syria prior to its 2019 collapse.
"This strike shows our UK leadership, and resolve to operate in unison with allied nations, to eliminate any re-emergence of Daesh and their dangerous and violent ideologies in the area," the British Defence Secretary John Healey remarked.
RAF aircraft have conducted overwatch operations over Syrian airspace to "deter any attempted resurgence" of Islamic State after its military defeat at the Baghuz confrontation in 2019, the ministry said.
"I want to thank the personnel of the UK armed forces who took part in this operation for their professionalism and their bravery," he said. "Including them were thousands of UK service members on duty over the holidays. This operation, to remove militants who pose a risk to our safety, demonstrates how British military are always on standby, throughout the year, protecting the UK domestically and strong abroad."
In December, the United States armed forces carried out what it described as a "major assault" targeting Daesh sites in the country, following an attack resulted in the deaths of two American soldiers and a local interpreter in Palmyra.
The UN estimates Daesh still has between 5,000 and 7,000 fighters in Syria and Iraq.
