The United Nations says more than a million people have fled the conflict in South Sudan to Uganda.

Nearly as many have travelled to neighbouring countries, making it the worst refugee crisis in Africa since the 1994 Rwandan genocide.

Fighters loyal to President Salva Kiir and troops under the former vice president Riek Machar have fought each other since 2013.

Tens of thousands of people have been killed since then, and nearly a third of the population has been displaced.

Al Jazeera's Malcolm Webb reports from a refugee centre near the Uganda-South Sudan border.
