After a stunning rebuke from Greek voters Sunday, European officials are expected to regroup on Tuesday to discuss what to do with the debt-riddled country.

French leaders and the European Council president called for a European Union summit in response to Greece's decision to reject a bailout Sunday that included new austerity measures, according to the Associated Press.

Greeks voted 61 percent to 39 percent with about 70 percent of the vote in to reject the bailout agreement on Sunday.

It remains to be seen whether Greece will exit the Eurozone, and what such a defection could do to U.S. markets. If Greece leaves the Eurozone then it will need to move to a new currency.

Greek officials had hoped to negotiate a new bailout agreement.

"Today's 'No' is a big 'Yes' to democratic Europe," said Greek Finance Minister Yanis Varoufakis in a press conference.

European officials disagreed.

Greek Prime Minister Alexis Tsipras and his government "are leading the Greek people on a path of bitter abandonment and hopelessness," according to German Economy Minister Sigmar Gabriel in Reuters.

Other European officials took a more optimistic tone, but still said the ball was in Greece's court.

"The Greek government has to explain how it sees the way forward, respecting European procedures," said Luxembourg Prime Minister Xavier Bettel in Reuters.
