Prime Minister Alexis Tsipras has said Greeks made a "brave choice" in voting to reject the terms of an international bailout in Sunday's referendum.

Thousands celebrated in the streets after hearing the final result was 61.3% "No", against 38.7% "Yes".

But European officials warned that it could see the country ejected from the eurozone and the euro fell across the board in Asian markets on Monday.

Greece's finance minister, who often clashed with creditors, has resigned.

Yanis Varoufakis wrote on his blog that he had been "made aware of a certain preference by some Eurogroup participants, and assorted 'partners', for my... 'absence' from its meetings".

The prime minister had judged this to be "potentially helpful to him in reaching an agreement", he noted, adding: "I shall wear the creditors' loathing with pride."

'No blackmail'

Greece's governing Syriza party had campaigned for a "No", saying that the bailout terms were humiliating.

Mr Tsipras said late on Sunday that the Greeks had proved that "democracy won't be blackmailed."

Speaking in a televised address, he said: "Given the unfavourable conditions last week, you have made a very brave choice.''

"But I am aware that the mandate you gave me is not a mandate for rupture.''

He said that Greece would go back to the negotiating table on Monday, adding that an International Monetary Fund (IMF) assessment published this week confirmed that restructuring Greek debt was necessary.

But some European officials had already warned that creditors could take a "No" vote to mean that Greeks had rejected further talks.

European leaders were varied in their openness to more talks with Greece after the vote.

Germany's Deputy Chancellor, Sigmar Gabriel, told local media that renewed negotiations with Greece were "difficult to imagine" and that Mr Tsipras had "torn down the bridges" between Greece and Europe.

However, Italian and Belgian ministers were more conciliatory, with Belgium's finance minister saying that the door remained open to restart talks "literally, within hours".

'Difficult time'

Jeroen Dijsselbloem, who heads the eurozone's group of finance ministers, said the referendum result was "very regrettable" for the future of Greece.

Meanwhile, Martin Schulz, the president of the European Parliament, warned that Europe was entering "a very difficult and even dramatic time" unless the Greek government made "meaningful" proposals in the coming hours.

Greece had been locked in negotiations with its creditors for months when the Greek government unexpectedly called a referendum on the terms it was being offered.
