Five people have been killed in xenophobic violence in South Africa, police said on Tuesday, as President Cyril Ramaphosa vowed to clamp down on the attacks and the African Union and Nigeria sounded their alarm.
Hordes of people -- some armed with axes and machetes -- gathered in Johannesburg's central business district (CBD) for a third day of unrest directed against foreigners, hours after mobs burned and looted shops in the township of Alexandra, prompting police to fire rubber bullets to disperse them.
Five deaths -- most of them South Africans -- have been reported, police said, adding that 189 people had been arrested.
In a video address diffused on Twitter, Ramaphosa said attacks on businesses run by "foreign nationals is something totally unacceptable, something that we cannot allow to happen in South Africa."
"I want it to stop immediately," said Ramaphosa, adding that the violence had "no justification."
