Hundreds of migrants and refugees are storming the roads near the Channel Tunnel in Calais, some 'armed with iron bars and hammers,' according to reports.

According to a vigilante group in the French port town, there have been clashes between riot police and migrants as dozens tried to storm the tunnel and climb into lorries in a bid to reach the UK.

Several videos uploaded by the group, calling themselves 'Angry Calaisians', shows dozens of people, mainly young men, runs across the roads.

The incidents have caused several traffic jams near the Channel Tunnel, with locals writing on social media that 'a group of six or seven migrants are running around with iron bars, stones and hammers' near a local supermarket.

An hour earlier, a post on the Facebook group claimed there was an 'attack of the tunnel by the illegal immigrants in progress!'

Later on, a group administrator added: 'A hundred illegals all on the way to the channel invading the roads! Be on your guard! Police in riot gear are at the scene!'

A number of men were also seen forcibly entering a handful of trucks and trailers which had been forced to stop.

The situation is dire in the migrant camp in Calais, known as 'The Jungle' where the population has more than tripled from around 1,500 in the summer.

It is believed some 7,000 may now be living in the camp's makeshift tents and shacks, as temperatures are set to plummet over the winter months.

Local hostility to the migrants has been growing, with the anti-immigrant National Front (FN) taking nearly half the votes in Calais in regional elections last weekend, their highest score in France.

With fewer and fewer migrants succeeding in making it to Britain, the camp with its barber shop, bars, Afghan biryani houses, Eritrean Orthodox church and Muslim prayer rooms, has taken on a semi-permanent air.
