British Air Force Typhoon fighter aircraft have conducted a mission with France's air force in a joint strike on an subterranean weapons facility in Syrian territory used by the Islamic State group (IS), as stated by the British defence ministry.
The site, located using reconnaissance, was thought to be containing munitions and bombs, the statement said, and was situated in mountains just north of Palmyra in central Syria.
"The RAF jets employed laser-guided Paveway IV weapons to hit a several entry passages providing entry to the site... initial indications are that the strike was effective," the ministry announced.
There was no evidence of any civilian impact in the attack late on Saturday and each participating jet made a safe return, the defence officials confirmed.
The Typhoon FGR4s were backed up by a Voyager tanker plane.
The Islamic State group - also known as ISIS - imposed militant control over large swathes of Syria and Iraq prior to its 2019 collapse.
"This strike shows the UK's leading role, and determination to work closely with our partners, to stamp out any resurgence of IS and their harmful and extremist ideologies in the region," the British Defence Secretary the Defence Secretary said.
UK warplanes have carried out surveillance missions over Syrian airspace to "forestall any attempted comeback" of Islamic State subsequent to its defeat at the battle of Baghuz in 2019, the ministry said.
"I want to thank every member of the UK armed forces involved in this mission for their expertise and their courage," Healey commented. "Including them were thousands of British troops on duty over the festive period. This action, to remove militants who endanger our security, highlights how British military are prepared to act, all year round, protecting the UK within its borders and strong abroad."
In December, the American forces executed what it called a "massive strike" on Daesh sites in the country, following an assault resulted in the deaths of two US servicemembers and a civilian interpreter in Palmyra.
The UN estimates Daesh still boasts between 5,000 and 7,000 fighters in Iraq and Syria.
