Those fleeing Kadugli are among an estimated seven million people who have been uprooted since the Sudanese Armed Forces and the paramilitary Rapid Support Forces began fighting in April. Two million have fled Khartoum, a city of five million people. In one week in August, another 300,000 entered neighbouring countries. The UN believes that 1.8m will seek refuge in camps in five countries bordering Sudan. On one night, 70,000 arrived in the Central African Republic. The need to provide shelter to refugees is stretching the UN’s humanitarian response budget, with reports of Sudanese families experiencing extreme hardship once they reach safety.
