ANC Malema hearing provokes unrest in Johannesburg
Police in South Africa have fired stun grenades to disperse crowds who have turned out to support a radical ANC leader facing a disciplinary hearing.
Julius Malema, once a close ally of Jacob Zuma, has become a fierce critic of the president and faces charges of creating divisions within the ANC and bringing the party into disrepute.
His supporters threw stones at police, who have erected a steel gate and barbed wire to close the main street leading to the African National Congress headquarters where the hearing is being held.
Karen Allen reports from Johannesburg.
