The United Nations says it needs another $3.3bn to deal with the Syrian refugee crisis up to the end of this year.

The UN humanitarian chief, Valerie Amos, told the BBC donor countries should look again at their contributions and be generous.

The UN estimates that two million Syrians have fled the country and another four million are internally displaced.

She said the crisis had implications for global peace and security because of the huge movement of people and the crisis following the chemical weapons attack.
