[Greek PM Tsipras attends a parliamentary session before a budget vote in Athens]Greek Prime Minister Alexis Tsipras said he would press fellow EU leaders at a summit on Thursday to end deadlock over plans to distribute some of the more than 60,000 asylum-seekers now in Greece. "We have to keep solidarity and make decisions for sharing the burden and the responsibilities," he told reporters on arrival, saying also that the EU should maintain the deal with Turkey which has largely halted the flow of migrants to Greece.
