Tusk tours Europe ahead of EU Summit

EU Council President Donald Tusk said in Athens that excluding Greece from the Schengen zone will not solve Europe's migrant problem, but acknowledged the crisis was testing European cohesion to its limits. "For all those talking of excluding Greece from Schengen, thinking this is a solution to the migration crisis, I say no, it is not. ... Let me be clear, excluding Greece from Schengen solves none of our problems," Tusk told reporters after meeting Prime Minister Alexis Tsipras in Athens. Donald Tusk is on a tour of European countries ahead of the EU summit, which begins on Thursday. After holding talks with the Romanian and French presidents on Monday, Tusk said negotiations on the possible Brexit are "difficult but… hugely important". "This is a critical moment. It is high time we started listening to each other's arguments more than to our own," Tusk said warning that "the risk of break-up is real because this process is indeed very fragile. Handle with care. What is broken cannot be mended."
