Riots that erupted in South Africa's capital continue in some areas, and at least one shop owned by immigrants has been attacked in a fresh wave of violence.

South African media reported Wednesday that residents of Pretoria's Mabopane area looted and ransacked shops. Reports say police fired rubber bullets to disperse a crowd and made some arrests.

The African News Agency, a South African media outlet, says a mob targeted a shop owned by Pakistani nationals.

The violence started in the Pretoria area Monday after the selection of the ruling party's mayoral candidate ahead of local elections on Aug. 3. Some residents say they were not adequately consulted about the selection.

The rioting has raised concerns about security ahead of municipal elections nationwide in August.
