Agreements reached by top diplomats earlier on Friday provided an opportunity that parties could not miss, Kerry said.
"If the international community and Syrians themselves miss the opportunity now before we to achieve that political resolution to the conflicts, the violence... will continue," he said.
Kerry said humanitarian aid could start flow to areas where in urgent need "today or tomorrow," while a lot of work must be done in order to ensure an effective "cessation of hostilities" within the week.
