Royal Marines are set to launch a mass evacuation of Brits living in the Middle East in similar style to Dunkirk during WWII.

Commandos have already probed the Lebanese coastline ahead of a potential maritime rescue mission.

The plan, codenamed Operation Meteoric, will be spearheaded by the Green Berets and will be supported by the Royal Navy and Royal Air Force.

It has been likened to Operation Dynamo, which saw the evacuation of hundreds of thousands of allied soldiers from Dunkirk in 1940 when they were surrounded by German forces following their Blitzkrieg campaign in France.

Speaking to the Daily Mail earlier this week, Defence Secretary Grant Shapps confirmed he "stands ready" to assist any Britons trapped in the region.

This was done prior to the Iranian drone attack on Israel late last night.

The publication has claimed that a party of Marines from 30 Commando arrived in the region in recent days.

The Foreign Office has already advised all British citizens to leave Lebanon.
