British Air Force Typhoon FGR4s have conducted a mission with French aircraft in a combined operation on an hidden munitions depot in Syria employed by the Islamic State group (IS), according to the UK's MoD.
The site, pinpointed through reconnaissance, was assessed as storing arms and explosives, the release indicated, and was located in mountains just north of the historic site of Palmyra in the heart of Syria.
"Our fighter planes used precision-guided Paveway IV munitions to target a series of entry passages leading to the depot... preliminary assessments indicate the strike was effective," the ministry announced.
There was no sign of any harm to civilians in the strike late on Saturday and every plane involved returned safely, the ministry further stated.
The British jets were assisted by a Voyager aerial refuelling aircraft.
IS - alternatively referred to as the so-called Islamic State - established extremist governance over parts of Iraq and Syria before its territorial defeat in 2019.
"This operation shows British leadership, and determination to operate in unison with our allies, to eradicate any re-emergence of the terrorist group and their harmful and extremist ideologies in the Middle East," UK Defence Secretary John Healey said.
RAF aircraft have carried out surveillance missions over Syria to "prevent any attempted comeback" of IS subsequent to its defeat at the Baghuz confrontation in 2019, the ministry said.
"I want to thank the personnel of our armed forces who took part in this strike for their professionalism and their courage," he commented. "They were among thousands of UK service members stationed over the festive period. This action, to remove militants who pose a risk to our way of life, shows how UK forces are prepared to act, throughout the year, keeping Britain secure domestically and powerful internationally."
In December, the US military executed what it termed a "massive strike" targeting Daesh sites in the country, following an assault killed two US servicemembers and a civilian linguist in Palmyra.
The United Nations estimates IS still boasts roughly 5-7 thousand fighters in both countries.
