In Sudan, fighting has again intensified in and around the capital Khartoum as the governor of West Darfur has been assassinated.

Governor Khamis Abakar was abducted by gunmen after a TV interview in which he accused the paramilitary fighters of genocide and called for international intervention.

The United Nations said the conflict has so far displaced more than 2 million people and escalating attacks in Darfur could amount to crimes against humanity.
