RAF Typhoon FGR4s have joined forces with French warplanes in a coordinated attack against an subterranean weapons facility in Syrian territory operated by the IS group, according to the UK Ministry of Defence.
The facility, pinpointed through surveillance, was believed to be housing weapons and explosive materials, the release indicated, and was situated in mountainous terrain just above the historic site of Palmyra in the heart of Syria.
"Our fighter planes used laser-guided Paveway IV weapons to strike a series of approach shafts leading to the depot... early reports suggest the objective was successfully hit," the MoD said.
There was no sign of any civilian casualties in the strike conducted Saturday night and each participating jet returned safely, the ministry further stated.
The British jets were backed up by a Voyager refuelling tanker.
Daesh - alternatively referred to as ISIS - imposed extremist governance over parts of Syria and Iraq until 2019.
"This strike demonstrates British leadership, and determination to operate in unison with allied nations, to stamp out any resurgence of the terrorist group and their violent and radical beliefs in the Middle East," Britain's Defence Chief the minister remarked.
UK warplanes have performed overwatch operations over Syrian airspace to "prevent any attempted resurgence" of the group subsequent to its military defeat at the climactic battle in Baghuz in 2019, the ministry said.
"I extend gratitude to every member of our armed forces participating in this strike for their professionalism and their bravery," Healey commented. "They were part of numerous UK service members deployed over the festive period. This mission, to take out militants who pose a risk to our way of life, shows how British military are prepared to act, throughout the year, keeping Britain secure within its borders and strong abroad."
During December, the US military conducted what it called a "large-scale strike" on Islamic State objectives in Syria, subsequent to an attack killed two US servicemembers and a civilian interpreter in the Palmyra area.
The UN estimates Islamic State still maintains roughly 5-7 thousand combatants in Iraq and Syria.
