Dozens of Calais migrants try to storm Channel Tunnel
Channel Tunnel services have been disrupted after about 150 migrants tried to storm the Calais terminal. Migrants entered restricted areas on the French side overnight, delaying and cancelling services, Eurotunnel said.
A spokesman for the firm called for "immediate action" from authorities to protect the tunnel and provide a solution to the migrant crisis.
Passenger services are back to normal but there are still delays to freight journeys, Eurotunnel said.
Freight lorries are queuing on the M20 for the second time this week.
Kent Police initiated phase two of Operation Stack - where freight traffic is queued on sections of the M20 - and closed roads at about 01:00 BST, according to BBC.com.
