Thousands of migrants have sought to reach England from France over the years.
Two years ago, French officials closed down a makeshift "Jungle" camp in the port city of Calais that had upwards of 6,000 migrants. Officials have since tried to stop smaller camps from popping up.
Many of the migrants sought to hop on trucks taking rail ferries or trains to England, where they have family.
The Channel has witnessed a recent spike in unsafe rubber boats and dinghies attempting to cross from France to Britain.
