Hopes have been raised for peace in South Sudan after the meeting on Wednesday between the country's President Salva Kiir and his former deputy Riek Machar, the first between the bitter rivals for two years.

The BBC has gained rare access to report from the country, the most dangerous place in the world to be an aid worker.
