South Africa's president says a total of seven people have died in ongoing attacks on immigrants here and he postponed a key ceremony because of the crisis.

The office of President Jacob Zuma said Monday that the ceremony scheduled for next week bestows the country's highest official honor on South Africans and foreigners who have contributed to South Africa. His office said it must be postponed so South Africa can mourn the victims of anti-immigrant violence.

The annual ceremony was to be held on April 27, a holiday commemorating the first all-race elections in 1994 that marked the end of apartheid.

Police in Durban say six people died in attacks there. South Africa's Sunday Times newspaper published photographs of a fatal attack in the Johannesburg area on a Mozambican man.
