ATHENS — Greece’s international bailout program has hit snags, delaying release of the next payout of rescue money.

Despite a weekend of negotiations by telephone, Greek officials and the country’s foreign creditors remained at odds. At a meeting in Brussels on Monday, eurozone finance ministers debated whether Athens had met the first set of conditions to unlock the next installment of the bailout of 86 billion euros (about $92 billion).

The ministers decided to delay the release of the payout, a sum of €2 billion, but indicated it might be dispensed soon.

Jeroen Dijsselbloem, the head of the eurozone finance ministers, used his Twitter account after the meeting to reinforce pressure on Athens to meet its targets, saying there had been a “commitment of the Greek authorities to fulfill the required measures in the course of the week.”
