Keira Knightley has described the "horrendous" conditions inside a refugee camp in South Sudan.
Thousands of people have been killed in the country since December and one and a half million are homeless.
The actress visited a camp in Bor for Oxfam, and told 5 live reporter Stephen Chittenden about the "desperate need" of the people she met.
She recalled being particularly affected by a recently widowed woman, called Rebecca, who explained how much she missed the way her husband held her.
First broadcast on BBC Radio 5 live's Victoria Derbyshire programme on 9 July 2014.
