Syria crisis: Food aid 'cannot reach a million people'

The World Food Program (WFP) says it is helping 1.5 million Syrians, but continued fighting and an inability to use the port of Tartus to deliver food mean many people are not receiving aid.

Opposition forces have been making considerable gains in recent weeks, but their efforts to take control of areas around major cities including Damascus have met with stiff resistance and increasingly destructive air strikes.
