Eurozone finance ministers met in a desperate bid to find a solution to the Greece debt crisis amid deadlock between Athens and its creditors.
Earlier talks between Greece's Prime Minister, Alexis Tsipras, and the country's international lenders ended without agreement.
Ahead of the Eurogroup meeting, the German finance minister warned that the gap between the two sides was widening.
Greece must repay a €1.6bn (£1.1bn) IMF loan by next Tuesday or face default.
That could lead to Greece exiting the eurozone, with possible repercussions for the rest of Europe and the world economy.
Only once agreement is reached will the European Commission, the European Central Bank (ECB) and the International Monetary Fund (IMF) unlock the final €7.2bn tranche of bailout funds for cash-strapped Greece.
The crisis threatens to overshadow a summit of EU leaders opening on Thursday afternoon.
