British Air Force Typhoon jets have joined forces with France's air force in a combined operation on an underground arms cache in Syria employed by the Daesh militant organization, per a report from the UK's MoD.
The facility, pinpointed through surveillance, was assessed as housing weapons and explosive materials, the statement said, and was situated in mountains just above Palmyra in central Syria.
"Our aircraft used Paveway IV guided bombs to strike a number of access tunnels leading to the site... initial indications indicate the objective was successfully hit," the ministry announced.
There was no sign of any civilian impact in the attack late on Saturday and each participating jet made a safe return, the MoD added.
The British jets were assisted by a Voyager refuelling tanker.
Daesh - alternatively referred to as ISIS - imposed jihadist rule over significant areas in both Syria and Iraq before its territorial defeat in 2019.
"This strike shows British leadership, and commitment to stand shoulder to shoulder with allied nations, to stamp out any resurgence of Daesh and their harmful and extremist ideologies in the Middle East," UK Defence Secretary John Healey said.
UK warplanes have performed overwatch operations over Syria to "prevent any attempted resurgence" of Islamic State after its military defeat at the climactic battle in Baghuz in 2019, the MoD reported.
"I want to thank the personnel of British forces participating in this strike for their professionalism and their courage," the Defence Secretary commented. "They were part of thousands of British troops on duty over Christmas and New Year. This action, to take out terrorist threats who pose a risk to our safety, shows how our armed forces are always on standby, continuously, ensuring Britain's security within its borders and powerful internationally."
During December, the United States armed forces executed what it termed a "large-scale strike" against Islamic State objectives in the country, subsequent to an attack killed two US troops and a civilian interpreter in the Palmyra area.
The United Nations estimates Islamic State still maintains roughly 5-7 thousand fighters in both countries.
