RAF Typhoon FGR4s have conducted a mission with France's air force in a joint strike against an subterranean weapons facility in Syria employed by the Daesh militant organization, as stated by the UK Ministry of Defence.
The site, located using surveillance, was assessed as containing munitions and bombs, the release indicated, and was located in mountainous terrain just above Palmyra in the heart of Syria.
"Our aircraft utilized Paveway IV guided bombs to strike a several entry passages down to the site... early reports suggest the strike was effective," the ministry announced.
There was no sign of any harm to civilians in the operation conducted Saturday night and all the aircraft returned to base without incident, the defence officials confirmed.
The British jets were assisted by a Voyager aerial refuelling aircraft.
IS - alternatively referred to as Daesh - imposed jihadist rule over large swathes of both Syria and Iraq until 2019.
"This strike demonstrates the UK's leading role, and commitment to operate in unison with our allies, to eradicate any re-emergence of IS and their harmful and extremist ideologies in the region," the British Defence Secretary the minister stated.
UK warplanes have conducted surveillance missions over Syria to "forestall any attempted comeback" of Islamic State following its routing at the battle of Baghuz in 2019, the MoD reported.
"I extend gratitude to every member of British forces involved in this strike for their professionalism and their bravery," Healey commented. "Including them were thousands of British troops on duty over the holidays. This mission, to take out dangerous terrorists who threaten our way of life, shows how British military are always on standby, throughout the year, keeping Britain secure at home and powerful internationally."
Last December, the United States armed forces conducted what it described as a "large-scale strike" against IS targets in the country, subsequent to an attack resulted in the deaths of two US servicemembers and a civilian interpreter in the Palmyra area.
The United Nations reports Islamic State still boasts between 5,000 and 7,000 combatants in Iraq and Syria.
