British Air Force Typhoon FGR4s have conducted a mission with French warplanes in a joint strike on an hidden munitions depot in Syria operated by the IS group, as stated by the UK Ministry of Defence.
The site, located using surveillance, was assessed as storing arms and explosives, the release indicated, and was situated in mountainous terrain just above the historic site of Palmyra in the heart of Syria.
"Our aircraft utilized laser-guided Paveway IV weapons to strike a several access tunnels leading to the site... initial indications indicate the target was engaged successfully," the MoD said.
There was no evidence of any civilian impact in the strike conducted Saturday night and every plane involved returned to base without incident, the MoD added.
The Typhoon fighters were assisted by a Voyager tanker plane.
IS - referred to as ISIS - established jihadist rule over parts of Iraq and Syria prior to its 2019 collapse.
"This strike demonstrates British leadership, and resolve to work closely with our allies, to stamp out any resurgence of Daesh and their harmful and extremist ideologies in the region," the British Defence Secretary John Healey said.
British military aircraft have conducted surveillance missions over Syria to "forestall any efforts to regroup" of the group following its routing at the climactic battle in Baghuz in the year 2019, the MoD reported.
"I must thank all the members of the UK armed forces participating in this mission for their expertise and their bravery," the Defence Secretary said. "They were among thousands of British troops stationed over Christmas and New Year. This operation, to take out militants who endanger our safety, demonstrates how our armed forces are always on standby, throughout the year, ensuring Britain's security within its borders and strong abroad."
Last December, the United States armed forces executed what it termed a "massive strike" on IS targets in the country, subsequent to an assault claimed the lives of two US servicemembers and a local interpreter in Palmyra.
The UN says Islamic State still maintains between 5,000 and 7,000 militants in Syria and Iraq.
