Combined Anglo-French Aerial Assault Targets Daesh Munitions Store in the Syrian region

British Air Force Typhoon fighter aircraft have joined forces with France's air force in a coordinated attack against an underground arms cache in Syria employed by the Islamic State group (IS), per a report from the British defence ministry.

The facility, located using surveillance, was believed to be housing weapons and explosive materials, the release indicated, and was situated in mountains just above the historic site of Palmyra in Syria's central region.

"The RAF jets employed precision-guided Paveway IV munitions to target a series of entry passages providing entry to the site... early reports are that the target was engaged successfully," the ministry announced.

There was no evidence of any civilian casualties in the attack conducted Saturday night and each participating jet made a safe return, the defence officials confirmed.

The Typhoon fighters were backed up by a Voyager refuelling tanker.

IS - also known as ISIS - established jihadist rule over parts of both Syria and Iraq prior to its 2019 collapse.

"This action shows British leadership, and commitment to work closely with our allies, to eradicate any resurgence of IS and their violent and radical beliefs in the area," UK Defence Secretary John Healey remarked.

UK warplanes have carried out patrols over Syrian airspace to "deter any attempted comeback" of IS following its defeat at the climactic battle in Baghuz in 2019, the MoD reported.

"I want to thank the personnel of British forces participating in this strike for their expertise and their courage," he commented. "Including them were a great many British personnel deployed over the holidays. This operation, to remove militants who pose a risk to our safety, highlights how UK forces are prepared to act, continuously, ensuring Britain's security within its borders and influential overseas."

Last December, the United States armed forces conducted what it called a "massive strike" against Islamic State objectives in Syria, following an assault resulted in the deaths of two US servicemembers and a local interpreter in Palmyra.

The UN estimates Daesh still has an estimated 5,000 to 7,000 militants in Iraq and Syria.
