Royal Air Force Typhoon fighter aircraft have joined forces with French warplanes in a combined operation on an underground arms cache in Syrian territory used by the Islamic State group (IS), as stated by the UK's MoD.
The site, located using surveillance, was assessed as storing arms and explosives, the release indicated, and was positioned in hills just to the north of Palmyra in Syria's central region.
"Our aircraft used Paveway IV guided bombs to hit a several access tunnels down to the depot... preliminary assessments suggest the strike was effective," the MoD said.
There was no sign of any harm to civilians in the operation conducted Saturday night and every plane involved made a safe return, the MoD added.
The Typhoon fighters were backed up by a Voyager tanker plane.
Daesh - referred to as Daesh - established jihadist rule over parts of both Syria and Iraq before its territorial defeat in 2019.
"This action underscores British leadership, and resolve to work closely with allied nations, to stamp out any re-emergence of IS and their harmful and extremist ideologies in the Middle East," UK Defence Secretary the Defence Secretary said.
British military aircraft have performed surveillance missions over Syria to "deter any efforts to regroup" of Islamic State subsequent to its defeat 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 expertise and their courage," he added. "Including them were thousands of UK service members stationed over the festive period. This action, to remove dangerous terrorists who endanger our way of life, shows how British military are ready to step up, all year round, keeping Britain secure at home and influential overseas."
In December, the US military carried out what it termed a "major assault" against IS targets in Syria, subsequent to an assault claimed the lives of two US troops and a civilian linguist in the Palmyra area.
The United Nations reports Islamic State still maintains between 5,000 and 7,000 militants in Syria and Iraq.
