'Greece only weeks away from cash crisis' - finance minister

Greece's finance minister says his country's financial situation is "terribly urgent" and the crisis could come to a head in a couple of weeks.

Yanis Varoufakis gave the warning after eurozone finance ministers met in Brussels to discuss the final €7.2bn tranche of Greece's €240bn EU/IMF bailout.

Ministers said Greece had made "progress" but more work was needed.

The Greek government is struggling to meet its payment obligations. Earlier, Greece began the transfer of €750m in debt interest to the International Monetary Fund - a day ahead of a payment deadline.

"The liquidity issue is a terribly urgent issue. It's common knowledge, let's not beat around the bush," Varoufakis told reporters in Brussels.

"From the perspective [of timing], we are talking about the next couple of weeks."

Greece has until the end of June to reach a reform deal with its international creditors. Its finances are running so low that it has had to ask public bodies for help. The crisis has raised the prospect that Greece might default on its debts and leave the euro.

The eurozone is insisting on a rigorous regime of reforms, including cuts to pensions, in return for the bailout, but Greece's anti-austerity Syriza-led government is resisting the tough terms.
