British Air Force Typhoon fighter aircraft have operated alongside France's air force in a combined operation on an underground arms cache in Syrian territory operated by the IS group, according to the British defence ministry.
The location, located using surveillance, was assessed as containing munitions and bombs, the release indicated, and was situated in mountainous terrain just to the north of the historic site of Palmyra in the heart of Syria.
"Our fighter planes used precision-guided Paveway IV munitions to target a series of approach shafts leading to the site... preliminary assessments are that the target was engaged successfully," the ministry announced.
There was no indication of any civilian casualties in the attack conducted Saturday night and every plane involved returned to base without incident, the defence officials confirmed.
The British jets were assisted by a Voyager tanker plane.
Daesh - alternatively referred to as ISIS - enforced extremist governance over significant areas in Syria and Iraq prior to its 2019 collapse.
"This operation demonstrates British leadership, and determination to operate in unison with our partners, to eliminate any resurgence of the terrorist group and their harmful and extremist ideologies in the Middle East," the British Defence Secretary the Defence Secretary remarked.
British military aircraft have conducted surveillance missions over Syrian airspace to "deter any attempted resurgence" of IS subsequent to its routing at the climactic battle in Baghuz in 2019, the ministry said.
"I extend gratitude to every member of our armed forces involved in this mission for their professionalism and their valour," Healey commented. "They were among a great many UK service members stationed over the holidays. This operation, to eliminate terrorist threats who threaten our way of life, shows how British military are always on standby, continuously, keeping Britain secure at home and influential overseas."
Last December, the United States armed forces executed what it called a "major assault" on IS targets in Syria, subsequent to an assault killed two US servicemembers and a civilian interpreter in Palmyra.
The U.N. says Islamic State still boasts roughly 5-7 thousand fighters in both countries.
