Crunch talks to resolve a five-month standoff between Greece and its EU-IMF creditors ended Thursday without a deal, Valdis Dombrovskis, the European Commission vice-president for the euro, said on Thursday.

"No deal at Eurogroup," Dombrovskis said in a tweet after the talks broke up after 90 minutes of discussion on Greece.

"Strong signal for Greece to engage seriously in negotiations. The Eurogroup stands ready to reconvene at any moment," he added.
