Greek Prime Minister Alexis Tsipras will meet leaders of Athens' three international creditors Monday ahead of an emergency eurozone summit on the Greek debt crisis in Brussels, a Greek government source said.

Council of Europe head Donald Tusk called the meeting with European Commission President Jean-Claude Juncker, International Monetary Fund chief Christine Lagarde and European Central Bank leader Mario Draghi, as well as the head of Eurogroup finance ministers, Jeroen Dijsselbloem, the source said Sunday.
