Brawl of Stalingrad: Fierce battle erupts at migrant camp under Paris metro station (VIDEO)

A shocking video has been released showing violent scenes which took place as a mass brawl broke out between migrants under the Stalingrad metro in Paris.

At least four people were seriously injured and the area has been completely overwhelmed by the fierce battle.

Hundreds of migrants can be seen attacking each other with metal poles, planks of wood and other debris in an alarming video, recorded by residents from a close by building.

The melee erupted Thursday night at around 9:00pm after after police arrested a man for being drunk and disorderly, according to Le Parisien.

The brawl subsides only after police fire tear gas canisters. However, clashes break out again around 11.30pm between “hundreds of very excited people who decide to fight,” police told Le Parisien.

A local resident who spoke to the publication said “there never had been violence until now.” Some 1,000 migrants, mainly from Eritrea, Sudan and Afghanistan set up camp there in early March after the demolition of the Calais “Jungle” camp.

The camp has been evacuated on two occasions in recent weeks. French Interior Minister Bernard Cazeneuve announced the removal of the camp on March 30 in a joint statement with Paris Mayor Anne Hidalgo, but the migrants returned with makeshift mattresses two weeks later, according to Le Parisien.

Police said Friday “investigators were still unaware” of the cause of the violence.
