The United Nations describes the humanitarian situation in Syria as unrelentingly distressing and dire.
The agency says more than 13 million people need some form of aid, but the fighting is making it difficult for assistance to reach civilians.
France and Britain are pushing for airdrops, but the UN says that should be a last resort, and not a susbstitute for land deliveries.
It estimates that more than half a million people are living under siege, but some groups put that figure at more than one million.
The UN has accused both the government and rebels of preventing aid delivery.
With so many actors involved, and different agendas, is there still a political way out of the Syria crisis?
