About 2,000 migrants tried to enter the Channel Tunnel through the French terminal near Calais Monday night in an attempt to reach the UK, operator Eurotunnel says.
Some of the migrants were injured, Eurotunnel France spokesperson Cecile Carreras told CNN.
The tunnel runs 31 miles from a point near Calais, in northern France to Folkestone, in southeastern England.
Calais has long been a gathering place for migrants trying to find a way into the UK.
