Work to clear part of the so-called Calais "Jungle" camp has restarted after a first day of demolitions saw fierce clashes between migrants and police.
Humanitarian workers condemned the actions of French authorities after tear-gas was fired during the demolitions.
The camp is a temporary home to around 4,000 people, many of whom are hoping to reach Britain.
Demolition teams have moved in to begin dismantling homes at the Calais "Jungle" camp after a court ruling cleared the way for mass evictions.

The Help Refugees charity said police blocked entrances to the camp, which is thought to hold around 4,000 people in makeshift homes.
