Royal Air Force Typhoon jets have conducted a mission with France's air force in a coordinated attack against an underground arms cache in Syrian territory employed by the IS group, according to the British defence ministry.
The site, pinpointed through surveillance, was believed to be storing arms and explosives, the announcement noted, and was located in hills just above the historic site of Palmyra in the heart of Syria.
"Our fighter planes used laser-guided Paveway IV weapons to hit a number of approach shafts leading to the facility... early reports are that the objective was successfully hit," the ministry announced.
There was no sign of any civilian impact in the operation conducted Saturday night and all the aircraft returned to base without incident, the defence officials confirmed.
The Typhoon FGR4s were assisted by a Voyager tanker plane.
The Islamic State group - also known as ISIS - imposed extremist governance over significant areas in both Syria and Iraq before its territorial defeat in 2019.
"This operation demonstrates British leadership, and determination to work closely with our allies, to eliminate any resurgence of IS and their violent and radical beliefs in the region," UK Defence Secretary the Defence Secretary said.
RAF aircraft have performed patrols over Syrian airspace to "prevent any attempted comeback" of Islamic State subsequent to its defeat at the battle of Baghuz in the year 2019, the MoD reported.
"I must thank the personnel of our armed forces involved in this strike for their expertise and their courage," Healey commented. "They were part of numerous UK service members on duty over Christmas and New Year. This operation, to remove dangerous terrorists who endanger our way of life, shows how our armed forces are prepared to act, continuously, protecting the UK at home and powerful internationally."
In December, the American forces carried out what it termed a "major assault" against Islamic State objectives in Syria, subsequent to an attack claimed the lives of two US servicemembers and a local interpreter in the Palmyra area.
The UN says Daesh still maintains between 5,000 and 7,000 militants in both countries.
