Former peace envoy Kofi Annan called on the international community to "get its act together" and find a way to solve the war in Syria, before it the crisis spreads beyond its borders. He told BBC Radio 4:
"If the international community doesn't get its act together and find a way of pressuring the parties to give up their ambitions on the battlefield, we are going to see a situation where sectarian war will spread in Syria and probably go beyond its borders.
Syria is not Libya. Libya imploded, Syria will not implode but in all likelihood explode, and explode beyond its borders. That mosaic of Syria, if we tear it apart, is going to be very difficult to put together again."
UN and Arab League mediator, Lakhdar Brahimi is expected to meet Syrian President Bashar al-Assad in Damascus today.
Brahimi arrived in Syria on Thursday, his first trip to the country since taking up his post.
