At least 12 people have been killed in the South African city of Johannesburg since Friday in a wave of violence directed at immigrants, police say.
Police have used tear gas and rubber bullets to try to stop gangs of armed youths from attacking foreigners and looting and burning their property.
Five people were killed overnight in the area of Cleveland. Two of them were burned and the others beaten to death.
More than 50 were taken to hospitals with gunshot and stab wounds.
During the day, a church where about 1,000 Zimbabweans have been taking refuge was attacked.
Bishop Paul Veryn of the Central Methodist Church which was attacked told SABC radio: "We consider that the situation is getting so serious that the police can no longer control it."
As night fell, immigrants were streaming into one police station near downtown Johannesburg carrying whatever belongings
