Royal Air Force Typhoon FGR4s have operated alongside France's air force in a joint strike on an hidden munitions depot in Syria operated by the Islamic State group (IS), as stated by the British defence ministry.
The facility, located using surveillance, was believed to be housing weapons and explosive materials, the statement said, and was positioned in mountainous terrain just north of the ancient city of Palmyra in central Syria.
"Our fighter planes used precision-guided Paveway IV munitions to target a number of approach shafts providing entry to the site... initial indications are that the target was engaged successfully," the ministry announced.
There was no sign of any civilian casualties in the attack conducted Saturday night and every plane involved returned safely, the ministry further stated.
The Typhoon FGR4s were supported by a Voyager tanker plane.
IS - referred to as the so-called Islamic State - enforced jihadist rule over parts of Iraq and Syria prior to its 2019 collapse.
"This action demonstrates the UK's leading role, and commitment to stand shoulder to shoulder with our allies, to eliminate any resurgence of IS and their harmful and extremist ideologies in the Middle East," Britain's Defence Chief the minister stated.
British military aircraft have conducted surveillance missions over Syrian airspace to "forestall any attempted comeback" of the group following its military defeat at the Baghuz confrontation in 2019, the ministry said.
"I want to thank all the members of the UK armed forces involved in this operation for their skill and their valour," he said. "They were part of a great many British personnel deployed over the festive period. This mission, to take out terrorist threats who threaten our safety, highlights how our armed forces are prepared to act, throughout the year, protecting the UK within its borders and influential overseas."
During December, the American forces carried out what it termed a "large-scale strike" on Daesh sites in the country, following an attack resulted in the deaths of two US servicemembers and a local interpreter in the Palmyra area.
The U.N. reports IS still maintains between 5,000 and 7,000 fighters in both countries.
