Syria agreement 'must be delivered' - John Kerry

US Secretary of State John Kerry has accused the Syrian government of "blatantly violating" the nine-week Syria truce.

Speaking after talks in Geneva, Mr Kerry said it was also "imperative" that humanitarian workers were given "countrywide" access.
