RAF Typhoon FGR4s have operated alongside French aircraft in a combined operation targeting an subterranean weapons facility in Syria operated by the Islamic State group (IS), per a report from the British defence ministry.
The location, pinpointed through intelligence, was assessed as storing arms and explosives, the release indicated, and was located in mountainous terrain just above Palmyra in central Syria.
"Our aircraft used Paveway IV guided bombs to strike a several access tunnels leading to the site... initial indications indicate the strike was effective," the ministry announced.
There was no evidence of any civilian casualties in the strike on Saturday evening and each participating jet made a safe return, the defence officials confirmed.
The Typhoon FGR4s were assisted by a Voyager tanker plane.
Daesh - referred to as Daesh - enforced extremist governance over parts of Syria and Iraq until 2019.
"This action demonstrates the UK's leading role, and commitment to work closely with our partners, to eliminate any revival of the terrorist group and their harmful and extremist ideologies in the Middle East," the British Defence Secretary the minister remarked.
British military aircraft have performed patrols over Syria to "forestall any efforts to regroup" of the group subsequent to its defeat at the battle of Baghuz in 2019, the authorities noted.
"I want to thank all the members of British forces participating in this mission for their expertise and their courage," the Defence Secretary added. "They were part of numerous British troops deployed over the festive period. This action, to eliminate terrorist threats who threaten our security, highlights how British military are ready to step up, continuously, ensuring Britain's security at home and influential overseas."
Last December, the US military executed what it described as a "large-scale strike" targeting IS targets in Syria, following an ambush killed two US troops and a local interpreter in the Palmyra area.
The U.N. reports Islamic State still maintains an estimated 5,000 to 7,000 fighters in Iraq and Syria.
