British Air Force Typhoon FGR4s have operated alongside France's air force in a joint strike on an subterranean weapons facility in Syria operated by the Islamic State group (IS), as stated by the British defence ministry.
The site, identified by reconnaissance, was thought to be housing weapons and explosive materials, the release indicated, and was located in hills just above the ancient city of Palmyra in central Syria.
"Our fighter planes used Paveway IV guided bombs to strike a several access tunnels leading to the facility... preliminary assessments are that the objective was successfully hit," officials stated.
There was no sign of any civilian impact in the attack late on Saturday and all the aircraft made a safe return, the MoD added.
The Typhoon fighters were assisted by a Voyager refuelling tanker.
The Islamic State group - alternatively referred to as Daesh - enforced extremist governance over parts of both Syria and Iraq prior to its 2019 collapse.
"This strike demonstrates our UK leadership, and resolve to operate in unison with our allies, to stamp out any resurgence of the terrorist group and their harmful and extremist ideologies in the region," UK Defence Secretary the minister stated.
UK warplanes have performed overwatch operations over Syria to "deter any attempted comeback" of Islamic State following its defeat at the Baghuz confrontation in 2019, the MoD reported.
"I want to thank all the members of British forces involved in this strike for their skill and their valour," Healey commented. "They were among numerous British troops on duty over the holidays. This operation, to eliminate terrorist threats who threaten our security, demonstrates how British military are prepared to act, all year round, protecting the UK domestically and influential overseas."
During December, the US military carried out what it termed a "massive strike" targeting Islamic State objectives in the country, following an attack claimed the lives of two US servicemembers and a civilian interpreter in Palmyra.
The UN says Daesh still maintains between 5,000 and 7,000 fighters in Syria and Iraq.
