In the latest in our series on people's daily lives, Kaltoom Hamid Aseel (left) tells of her life in Kalma refugee camp in Darfur in western Sudan.
I am 27. My three children are sick with diarrhoea. We live in one hut with my sisters, Neimad (right), and Mona.
Neimad has two children. There are eight of us. My husband is dead. Neimadís husband was taken away. We have not seen him in months.
