Syria conflict: Jordan's Zaatari refugee camp from the air

Many of those forced to leave their homes during the Syrian conflict have taken refuge in neighbouring countries, and 80,000 of them are now living in a three-square-mile piece of the desolate Jordanian desert - home to the sprawling Zaatari refugee camp.

King Abdullah says his country is at "boiling point" because of the influx of refugees.

Chief international correspondent Lyse Doucet reports from Jordan on the scale of the crisis from a helicopter flying over the camp.
