The new UN-Arab League envoy on Syria, Lakhdar Brahimi, has given a deeply pessimistic view of the task ahead of him, as he takes up his new post.
Speaking to the BBC, the Algerian described his mission as "nearly impossible".
Mr Brahimi, a seasoned UN diplomat, was appointed after his predecessor, Kofi Annan, resigned, saying he no longer saw a way to fulfil his mission.
Fighting in Syria has escalated, despite a truce mediated by Mr Annan.
