Greece failed to reach an initial deal with the European Union and the IMF to unlock aid after the creditors dismissed a package of reforms from Athens as ideas rather than a concrete plan, officials said on Tuesday.

The lack of a deal further raises pressure on Athens, which faces the prospect of running out of money in a few weeks unless it can convince lenders to dole out more financial help.
