British Air Force Typhoon fighter aircraft have operated alongside France's air force in a coordinated attack targeting an subterranean weapons facility in Syria operated by the IS group, per a report from the British defence ministry.
The facility, pinpointed through reconnaissance, was believed to be housing weapons and explosive materials, the release indicated, and was positioned in mountains just above Palmyra in Syria's central region.
"Our fighter planes utilized Paveway IV guided bombs to hit a several access tunnels providing entry to the facility... initial indications are that the target was engaged successfully," the ministry announced.
There was no sign of any civilian casualties in the operation conducted Saturday night and every plane involved made a safe return, the defence officials confirmed.
The Typhoon FGR4s were supported by a Voyager aerial refuelling aircraft.
Daesh - alternatively referred to as the so-called Islamic State - established extremist governance over large swathes of Iraq and Syria until 2019.
"This strike underscores British leadership, and commitment to stand shoulder to shoulder with allied nations, to stamp out any resurgence of the terrorist group and their dangerous and violent ideologies in the Middle East," UK Defence Secretary the Defence Secretary remarked.
RAF aircraft have carried out surveillance missions over Syria to "forestall any attempted resurgence" of the group subsequent to its routing at the battle of Baghuz in the year 2019, the authorities noted.
"I extend gratitude to every member of British forces participating in this operation for their professionalism and their courage," he commented. "They were among a great many British troops stationed over the festive period. This operation, to eliminate terrorist threats who endanger our security, highlights how our armed forces are always on standby, continuously, ensuring Britain's security within its borders and strong abroad."
Last December, the American forces carried out what it called a "major assault" on Daesh sites in Syria, following an attack resulted in the deaths of two US servicemembers and a local interpreter in the Palmyra area.
The United Nations reports Islamic State still has roughly 5-7 thousand fighters in Iraq and Syria.
