A strike by dockworkers has forced the suspension of services through the Channel Tunnel between the UK and France, creating chaos as migrants try to board trucks caught in slow-moving traffic. Truck drivers have been advised to make sure all their doors are padlocked, to stick with other drivers and not to stop within about 60 miles of the port.
Workers from the MyFerryLink Company had blockaded the port of Calais in a protest over job cuts on Tuesday. The strike is preventing ships leaving or entering the port. About 3,000 migrants are estimated to be living rough around the French city of Calais, waiting for a chance to cross the channel.
