9,000 people have died in Sudan's six-month conflict, according to the UN relief chief

A powerful paramilitary organization and Sudan's military have killed up to 9,000 people in six months of war, creating “one of the worst humanitarian nightmares in recent history,” the UN humanitarian chief warned Sunday.

Sudan has been in upheaval since mid-April, when military head Gen. Abdel-Fattah Burhan and paramilitary Rapid Support Forces commander Gen. Mohamed Hamdan Dagalo fought.

Starting in Khartoum, the battle expanded across east Africa, including the conflict-torn western Darfur region.

Griffiths estimated up to 9,000 people were killed and millions were displaced to safer locations in Sudan or neighboring countries.

Conflict tore "communities apart," he claimed. Victims without lifesaving aid. Increased humanitarian needs in neighboring nations where millions have fled.”

Over 4.5 million Sudanese were displaced, and over 1.2 million fled to neighboring countries, according to the UN migration agency. Griffiths said 25 million people—more than half the country—needed humanitarian relief because to the war.

He stated more over 1,000 suspected cholera cases were found in Khartoum, Kordofan, and Qadarif, adding to the disaster.
