South Africa launches contentious road tolls

South Africa's contentious road toll system has opened around Johannesburg, with huge traffic jams as motorists flock to use alternative routes.

Opposition parties, trade unions and churches are calling for a boycott of the much-delayed system, saying it is unfair and badly designed.

The "e-toll" system affects the ring road around Johannesburg and the motorway to the capital, Pretoria.

The BBC's Milton Nkosi reports from Johannesburg.
