Kerry said that he and Lavrov agreed to meet on Monday morning to discuss differences on Syria.
"Everybody knows how complicated this issue [Syrian crisis] is, because of how many different forces are involved," Kerry told reporters after a meeting with Lavrov. "Therefore we decided to meet tomorrow to see if we can bridge differences on couple of issues."
"There still remains a couple of tough issues that we need to work on," he said, refusing to specify what the remaining sticking points are.
