Tens of thousands of people have been killed and 8.5 million have been forced to flee their homes a year after civil war erupted in Sudan. The northeast African country is experiencing "one of the worst humanitarian disasters in recent memory", the UN says. Experts see no end in sight to the fighting, which began on 15 April 2023 between the forces of two rival generals. Aid workers have called it the "forgotten war" affecting a country of 48 million people and leaving more than half the population in need of humanitarian assistance.
