British Air Force Typhoon jets have operated alongside France's air force in a joint strike on an subterranean weapons facility in Syrian territory employed by the IS group, as stated by the British defence ministry.
The facility, located using reconnaissance, was assessed as housing weapons and explosive materials, the statement said, and was located in mountains just north of Palmyra in the heart of Syria.
"The RAF jets employed Paveway IV guided bombs to target a series of access tunnels down to the depot... preliminary assessments indicate the target was engaged successfully," officials stated.
There was no indication of any harm to civilians in the attack conducted Saturday night and every plane involved returned safely, the defence officials confirmed.
The Typhoon fighters were assisted by a Voyager aerial refuelling aircraft.
Daesh - also known as ISIS - enforced extremist governance over parts of Iraq and Syria until 2019.
"This strike underscores British leadership, and commitment to work closely with our partners, to stamp out any resurgence of Daesh and their harmful and extremist ideologies in the Middle East," Britain's Defence Chief the Defence Secretary said.
UK warplanes have performed surveillance missions over Syrian airspace to "deter any efforts to regroup" of IS after its routing at the Baghuz confrontation in 2019, the ministry said.
"I must thank the personnel of British forces involved in this mission for their professionalism and their valour," the Defence Secretary commented. "Including them were numerous British troops on duty over the holidays. This action, to take out dangerous terrorists who threaten our way of life, shows how British military are always on standby, all year round, ensuring Britain's security at home and powerful internationally."
Last December, the American forces carried out what it described as a "major assault" on IS targets in the country, subsequent to an assault killed two US servicemembers and a local interpreter in Palmyra.
The United Nations estimates IS still has an estimated 5,000 to 7,000 fighters in both countries.
