Tshwane - From early Wednesday morning, taxi drivers blocked all major intersections in Mabopane, Ga-Rankuwa and Soshanguve, north of Pretoria, in a bid to prevent people from getting to work.
Reports of violence linked to the strike have come from the city's townships, with commuters left stranded on Wednesday morning.
Some roads are apparently blocked, and Mayor Solly Msimanga has said in a statement that train services have halted.
Reports were also received that some entrances to Mamelodi, east of Pretoria, were blocked.
The Pretoria CBD and routes the operators intend to use later on Wednesday when they hand over a memorandum of grievances to Mayor Solly Msimanga at Tshwane House, are meanwhile quiet and open to traffic.
