South Africans have disrupted a speech in Johannesburg by a veteran politician who was trying to quell tensions following a recent wave of deadly riots and xenophobic attacks.
Mangosuthu Buthelez was heckled by a rowdy section of the crowd.
Dozens of men marched through the area calling for foreigners to leave.
At least 10 people, two of them foreign nationals, have been killed in the violence over the last week.
By Thursday police said they had arrested more than 420 people and the unrest had subsided.
But on Sunday groups of men carrying clubs marched down the streets of Johannesburg singing “foreigners must go back to where they came from”, Soweten Live reports.
