More than 2,000 migrants have stormed Eurotunnel's French terminal in Calais in an attempt to reach the UK, causing delays to services as the UK announced an extra £7 million to tackle the crisis.

The operator said it was time for the Government to sort out the problem which has seen large numbers of migrants making ever more risky attempts to access the shuttles between France and the UK.

The latest attempt on Monday evening saw fences damaged in attempt to board the carriages in a freight terminal. A number of people were injured. Eurotunnel claimed the migrant flow is now much for the Government to handle.

A spokesman said: "It is an almost nightly occurrence. We're trying to run a travel business here."

Home Secretary Theresa May announced the extra £7 million funding which will be used to beef up security at the Channel Tunnel railhead in Coquelles.

She disclosed the extra funding following a meeting between British and French officials to discuss the continuing disruption.

She said: "We've had a very constructive meeting. The French and UK governments are working in close collaboration and cooperation on this issue which affects us both.

"We are both clear that we need to ensure we are dealing with the terrible criminal gangs, the people smugglers, who are making a profit out of the human misery of many people."

Mrs May said French authorities have committed extra resources to security at Calais.

Asked why British taxpayers should be paying for a problem taking place on French soil, she said: "We have juxtaposed controls at the border. We work together on dealing with this particular problem."

The Home Secretary said she was "very aware" of the impact of the crisis on lorry drivers, those affected by delays and the people of Kent.

An excerpt from a communique following today's conference said: "The UK and France agree it is vital we deal with the continuous migration of people from countries of origin.

"Both countries have agreed to work together on returning migrants to their countries of origin, particularly in West Africa."

Ms May recently announced that a new secure zone will be created at Calais for UK-bound lorries in response to an unprecedented surge in migrants attempting to cross the Channel.

The area will cost around two million euros (£1.4m) and is expected to be complete in the autumn.

Last autumn the Government pledged £12m to help France tackle the problem of illegal immigrants attempting to cross the Channel.

Meanwhile, Eurotunnel advised anyone taking a day-trip to France via its passenger services to "postpone their journey" due to long delays as a result of "migrant activity" throughout the night.
