JOHANNESBURG (Reuters) - South African police fired rubber bullets on Wednesday at stone throwing supporters of the ruling ANC who tried to confront members of the opposition Democratic Alliance party as they marched in central Johannesburg.
The incident is a sign of rising tensions in South Africa before general elections on May 7, which are seen as the biggest political test yet for President Jacob Zuma and his African National Congress (ANC), which has been in power for 20 years since the end of white apartheid rule.
