Hiba Morgan, a journalist of Sudanese and South Sudanese origin, is one of the few reporters still working in Sudan’s capital, Khartoum. She is the correspondent for Al Jazeera, and with her team she has documented at great peril the street-by-street fight between two rival generals and their troops to control the city and the country. The fighting has stretched on for more than three months, killing thousands of people. Her team had had many close calls — stray bullets and wayward artillery coming uncomfortably close. When I called her recently, she listened for incoming airstrikes or gun battles that ricocheted too close as we talked. I asked her what kept her here, when so many others had fled.
