Sudan braced Sunday for a mass protest in the capital against the country's ruling generals, as calls mounted for restraint to prevent a new military crackdown on demonstrators. The planned "million-man" march is seen as a test for protest organisers who have been hit by a June 3 raid on a Khartoum sit-in and a subsequent internet blackout that has curbed their ability to mobilise support.
