Ethnic cleansing is taking place in war-torn South Sudan, the UN Commission on Human Rights (UNCHR) has warned.

It says it has observed starvation, the burning of villages and rape being used as weapons of war across the country.

The three-member commission, which was established earlier this year, has just completed a 10-day visit to South Sudan, which has been blighted by conflict for more than three years.

President Salva Kiir has denied that ethnic cleansing is taking place.
