When an Arab militia rampaged through Maryam Suleiman’s village in the Darfur region of Sudan last year and lined up men and boys to massacre, the gunmen were blunt about their purpose.

“We don’t want to see any Black people,” a militia leader said, adding mockingly: “We don’t even want to see black trash bags.” To make his point, Maryam recalled, he shot a donkey because it was black.

Then the militia members executed men and boys who belonged to Black African ethnic groups, she said. “They shot my five brothers, one after the other,” Maryam told me, describing how her youngest brother survived the first bullet and called out to her. Then a militia member shot him in the head and sneeringly asked her what she thought of that.

The militia tried to systematically kill all the males over 10, Maryam said, and also killed some younger ones. A 1-day-old boy was thrown to the ground and killed, and one male infant was thrown into a pond to drown, she said.

The gunmen then rounded up the women and girls in a corral to rape, she added. “They raped many, many girls,” she recalled. One man tried to rape Maryam, she said, and when he failed he beat her. She was pregnant and suffered a miscarriage.

“You’re slaves,” Maryam quoted the militia members as saying. “There is no place for you Black people in Sudan.” So Maryam fled to neighboring Chad and is one of more than 10 million Sudanese who have been forcibly displaced since a civil war began last year in the country and ignited pogroms against Black African ethnic groups like hers.
