Images and video posted to Twitter purport to show an explosion following by the spreading of the fires, as police rushed to the scene.

More than 7,000 migrants from Syria, Afghanistan and parts of Africa are being moved to small centers across France after the country decided to demolish the camp, known for its cramped and squalid conditions.

As of this morning, the camp was completely clear of migrants.

"It's the end of the Jungle, our mission is over. There are no more migrants in the camp," Fabienne Buccio, the prefect of Pas-de-Calais, said, according to the BBC.

A migrant makes his way through a police cordon in the makeshift migrant camp known as "the jungle" near Calais, northern France, Oct. 24, 2016. French authorities are beginning a complex operation, unprecedented in Europe, to shut down the makeshift camp, uprooting thousands who made treacherous journeys to escape wars, dictators or grinding poverty and dreamed of making a life in Britain. #APPhoto by @thibaultcamus #migrants #France #Calais #thejungle #ThibaultCamus #AP #AssociatedPress #APImages #news #photojournalism
