Johannesburg - Thousands of ANC supporters gathered at Luthuli House after 1pm on Wednesday after violence flared up in central Johannesburg.
“Voetsak Zille” read placards being held by ANC supporters, who played loud music on Sauer Street.
Two stages were also erected.
Hawkers moved from other streets onto Sauer Street to get better business from the crowds gathered there.
Hawkers lined the street selling ANC regalia and merchandise.
Police were positioned at various points near the ANC's headquarters with water cannon.
A Nyala was also parked nearby.
Before midday, violence erupted during a march by the Democratic Alliance over “real jobs”.
Police stopped the march on Marshall and Rissik streets saying it was too dangerous for them to continue.
A short while later, a group of people wearing ANC attire ran towards the marchers forcing police to fire stun grenades at them.
On Miriam Makeba Street, a group, also dressed in ANC attire, threw petrol bombs at police.
ANC spokesman Jackson Mthembu said he was not aware of any violence.
“I didn't see any violence. I only see people running and marching,” he told Sapa.
“If there was any violence, we would condemn it... but from where I am seated our member have been well behaved. There was no threat from ourselves.”
