A resident attempts to extinguish a fire in a burning storeroom on church property set by angry residents protesting the replacement of Pretoria’s mayoral candidate in Atteridgeville, Pretoria, South Africa, Tuesday June 21, 2016. Rioters blocked roads, looted shops and burned vehicles Tuesday in several areas of the South African capital. The violence raised concerns about security ahead of the Aug. 3 elections in South Africa, where periodic unrest over the lack of basic municipal services already stretches police in many poor communities.
