BRUSSELS — Greece’s international creditors failed to agree Monday on how to get the country’s bailout program back on track and put off again the release of the next batch loans that Athens is using to pay its day-to-day bills.

However, European finance ministers meeting in Brussels did decide to give Greece two more years, until 2016, to reform its economy — one of the conditions of its bailout package. But they could not agree on how to pay for the extension or when the country’s debts would reach a manageable level.
