Thousands of people have fled fierce street battles in central Khartoum for Sudan’s borders, waiting for days in the open air to enter Egypt or walking hundreds of miles to cross into South Sudan.
Rana Ameen, a 23-year-old engineering student, said she and five members of her family had paid the equivalent of £475 per person to travel to the border crossing with Egypt, almost 600 miles (1,000km) away.
