RAF Typhoon FGR4s have conducted a mission with French aircraft in a joint strike targeting an subterranean weapons facility in Syria operated by the Daesh militant organization, per a report from the UK's MoD.
The site, pinpointed through reconnaissance, was believed to be housing weapons and explosive materials, the statement said, and was positioned in mountainous terrain just above the historic site of Palmyra in central Syria.
"Our aircraft used Paveway IV guided bombs to strike a series of access tunnels providing entry to the site... preliminary assessments suggest the strike was effective," the ministry announced.
There was no sign of any civilian casualties in the attack conducted Saturday night and every plane involved returned safely, the MoD added.
The Typhoon FGR4s were backed up by a Voyager tanker plane.
IS - also known as the so-called Islamic State - enforced jihadist rule over large swathes of Iraq and Syria until 2019.
"This strike shows British leadership, and resolve to work closely with allied nations, to eradicate any revival of Daesh and their dangerous and violent ideologies in the Middle East," Britain's Defence Chief the Defence Secretary said.
UK warplanes have carried out overwatch operations over Syria to "forestall any attempted resurgence" of the group subsequent to its military defeat at the battle of Baghuz in the year 2019, the ministry said.
"I want to thank every member of the UK armed forces involved in this strike for their professionalism and their courage," he commented. "Including them were thousands of British troops deployed over the holidays. This operation, to eliminate militants who endanger our way of life, highlights how our armed forces are always on standby, throughout the year, ensuring Britain's security within its borders and powerful internationally."
During December, the US military conducted what it described as a "massive strike" targeting Daesh sites in the country, following an assault claimed the lives of two US troops and a local interpreter in the Palmyra area.
The United Nations reports Daesh still boasts between 5,000 and 7,000 fighters in Syria and Iraq.
