ATHENS, Greece (AP) — Two days before a crucial summit of Eurozone leaders, Greek ministers are huddling to discuss strategy and assemble a new package of proposals, officials say.

A meeting between Prime Minister Alexis Tsipras and three senior ministers finished Saturday evening and a new one is scheduled for Sunday morning.

"We aim at an agreement" Monday, Economy Minister George Stathakis told reporters after leaving Saturday's meeting.

Minister of State Alekos Flambouraris said in a TV interview earlier Saturday that there could be a phone discussion between Tsipras and European Commission President Jean-Claude Juncker later Saturday, although it had not been scheduled yet.

The government on Saturday said Tsipras has cancelled a visit to Strasbourg Tuesday, where he was scheduled to speak at the Council of Europe.
