Joint British-French Airstrike Targets Daesh Arms Cache in the Syrian region

British Air Force Typhoon fighter aircraft have conducted a mission with France's air force in a coordinated attack on an underground arms cache in Syrian territory operated by the Daesh militant organization, per a report from the UK's MoD.

The facility, located using intelligence, was thought to be storing arms and explosives, the release indicated, and was situated in hills just above Palmyra in central Syria.

"The RAF jets utilized Paveway IV guided bombs to target a series of access tunnels down to the facility... initial indications are that the objective was successfully hit," officials stated.

There was no sign of any civilian casualties in the operation conducted Saturday night and every plane involved returned safely, the defence officials confirmed.

The British jets were assisted by a Voyager aerial refuelling aircraft.

Daesh - referred to as the so-called Islamic State - enforced militant control over large swathes of Syria and Iraq before its territorial defeat in 2019.

"This strike shows British leadership, and determination to operate in unison with allied nations, to eradicate any re-emergence of Daesh and their harmful and extremist ideologies in the region," UK Defence Secretary John Healey said.

British military aircraft have carried out surveillance missions over Syrian airspace to "prevent any efforts to regroup" of IS after its defeat at the climactic battle in Baghuz in 2019, the ministry said.

"I want to thank every member of the UK armed forces involved in this strike for their expertise and their bravery," he said. "They were part of thousands of UK service members deployed over the holidays. This mission, to remove dangerous terrorists who endanger our safety, highlights how British military are prepared to act, continuously, keeping Britain secure within its borders and influential overseas."

Last December, the US military carried out what it termed a "large-scale strike" against Islamic State objectives in Syria, following an assault claimed the lives of two US troops and a civilian interpreter in the Palmyra area.

The U.N. estimates Islamic State still maintains an estimated 5,000 to 7,000 militants in Syria and Iraq.
