Germany and Austria on Tuesday called for a special European summit on the migrant crisis, in a phone call with EU president Donald Tusk, said German Chancellor Angela Merkel.

"It is a problem for the entire European Union and therefore we argued for a special EU summit to be held next week," she said during a joint press conference with Austrian counterpart Werner Faymann. "Donald Tusk will look into that." Slovakia's prime minister echoed the call for EU to hold a special summit to deal with the biggest migration crisis in Europe since World War II.
