South African police say two suspected looters were fatally shot following a week of attacks on immigrant-owned shops in the Johannesburg area.

The South African Press Association on Monday quoted police Lt. Gen. Solomon Makgale as saying the two men were killed in Langlaagte, south of Johannesburg. Makgale says the men were part of a group that allegedly went to a Somali-owned shop to loot it on Sunday night.

It was not immediately clear who fired the shots that killed the men.

Looting and related violence in the past week in Soweto township and other areas around Johannesburg has killed a total of six people, including a baby who was trampled to death when a crowd stampeded outside a ransacked shop.
