German Chancellor Angela Merkel says that Greece has committed to work intensively with international creditors in coming days to resolve outstanding issues holding up its access to vital bailout loans.

The creditors have made clear that Greece must improve its offer of reforms it would introduce in exchange for 7.2 billion euros ($8.1 billion) in bailout loans it needs to repay debts due at the end of the month.

Merkel said Thursday that in overnight talks with Greek Prime Minister Alexis Tsipras a clear consensus emerged that "Greece will now work emphatically and at full steam with the three institutions in coming days to try to clear up all the outstanding issues."

Merkel expressed "hope that the necessary progress can now be made," and underlined that "each day counts."
