More than 1,500 civilians may have been massacred during an attack on Sudan’s largest displacement camp in April, in what would be the second-biggest war crime of the country’s catastrophic conflict.

A Guardian investigation into the 72-hour attack by the paramilitary Rapid Support Forces (RSF) on North Darfur’s Zamzam camp, the country’s largest for people displaced by the war, found repeated testimony of mass executions and large-scale abductions. Hundreds of civilians remain unaccounted for.
