South Africa's police and the ruling ANC party have intensified efforts to quell anti-foreigner violence that has killed at least 24 people and sent thousands of African immigrants into refugee shelters.
Police have struggled for over a week to end the violent attacks on foreigners who are accused by many in South Africa's poor townships of stealing jobs and fuelling a wave of violent crime.
Local media said two people were killed overnight.
Several foreigners have been burnt to death, women have been raped and scores of shops and homes looted.
More than 200 people have been arrested since the violence erupted on 11 May in Alexandra township.
The African National Congress said the situation was coming under control after it sent officials into townships to appeal for an end to the attacks.
Police also increased their deployment to trouble spots.
The unrest has increased political instability at a time of electricity shortages, rising inflation and disaffection among the poor over President Thabo Mbeki's pro-business policies.
South Africa, with a population of 50m, is home to an estimated 5m immigrants.
Foreigners from poorer countries have been lured by work in mines, farms and homes and by one of the world's most liberal immigration and refugee policies.
The biggest group, an estimated 3m, is from Zimbabwe.
They have fled economic collapse at home, and the violent political standoff since disputed 29 March elections gives them little incentive to return home.
