The US and the European Union have called on all sides in Egypt's political crisis to end "a dangerous stalemate" after the interim government said foreign mediation had failed.
In a joint statement, they said the Egyptian government bore a special responsibility to begin this process.
The army-backed government says it will break up sit-ins in Cairo being held by supporters of ousted President Morsi.
Scores have died in unrest since Mohammed Morsi was ousted on 3 July.
Since then, diplomats from the US, EU, Qatar and the United Arab Emirates have all tried to bring Egypt's political process back on track.
But on Wednesday the office of interim President Adly Mansour declared in a statement that the "phase of diplomatic efforts has ended today".
The presidency said it held the Muslim Brotherhood - which backs Mr Morsi - "completely responsible for the failure of these efforts".
The government statement came hours after US Deputy Secretary of State William Burns left Egypt following several days of mediation talks. He was assisted by EU envoy Bernardino Leon.
Shortly afterwards, US Secretary of State John Kerry and EU High Representative Catherine Ashton issued a joint statement.
