After years of tension in Darfur between nomadic Arab tribes and the African farmers they allegedly preyed on, two African groups rebelled last year, accusing Khartoum of arming the Janjaweed militias.
Khartoum has agreed to attend AU-mediated talks on Darfur in Ethiopia on July 15, but the rebels say they will not negotiate unless Sudan first disarms the marauding Arab militias and respects the ceasefire.
