Several thousand migrants took part in a violent victory march after French authorities performed a U-turn and scrapped plans to raze a huge section of the squalid shanty town to the ground. Hordes of hooded asylum seekers clashed with French riot police and yelled obscenities at terrified locals as they marched through Calais in the dark, unperturbed by heavy rain.

They were returning to the Jungle just days after being asked to leave so that a huge section of the crime and disease infested tent city could be bulldozed. Despondent locals who have endured years of terror and violent crime at the hands of migrant gangs filmed the carnage that unfolded on their mobile phones.

In the shocking footage migrants can be seen blocking up roads, yelling at residents and repeatedly chanting "UK!" as helpless French police watch on. One video, uploaded by the group of citizen journalists known as Calais Infos Vérités, is filmed from a car driving around Calais town centre last night. The film begins showing a police car pursuing a group migrants who are running through the streets of the historic port town.

As the car turns a corner into the main square, a hooded gang can be seen walking past a supermarket with one migrant appearing to stick two fingers up to the cameraman. Later on the vehicle passes a Total petrol station which has been overwhelmed by an intimidating group of migrants, with the narrator describing the atmosphere as "tense". They walk out into the street, forcing the car to slow, with some raising their arms and yelling "go UK!" at the driver as he passes. The film then moves on to a scene on a motorway bridge, near the Calais Jungle camp, where migrants can be seen clashing with French police who appear to have used tear gas in a bid to restore order.

Clouds of white smoke drift through the air and there is panicked shouting as a group of migrants dash down the street against the reflection of flashing blue lights. The video is captioned: "The night of the 24th to 25th of February has been very tense. Around 1,000 to 1,500 illegal immigrants took part in an assault of the streets of Calais. "You can see in this video different scenes filmed on the spot. The police did not know which way to turn." Another video showed "thousands" of migrants returning to the Jungle after the demolition was postponed.

The video finishes with a clip of the car driving down a main road which is completely blocked up by migrants walking the other way. The narrator gloomily states that Calais has "returned to square one" after French authorities decided to postpone the destruction of the Jungle camp. As the lights from a police car flash in the distance a group of migrants surround the car, slowing it down to a crawl, yelling "UK, UK, UK" and "thank you" loudly. In a separate video, also taken from a car and posted on the Les Calaisiens en Colère Facebook page, thousands of migrants can be seen streaming along a road back towards the Jungle.
