The R59 highway in Vereeniging has been blocked with trucks and cars in support of the Black Monday campaign to highlight the high number of farm murders.
The movement was started in Cape Town by a group called Enough is Enough after the murder of farmer Joubert Conradi e on his farm earlier this month.
According to motorists, supporters dressed in black are causing major traffic congestion in the Vereeniging area.
Meanwhile, AfriForum’s Ernst Routs says that they are supporting a meeting in Pretoria but is not organising the protests.
Civil society action against the killing of farmers will start on Monday in parts of the country.
According to AfriForum, there have been 70 fatal attacks on farmers since January.
Police Minister Fikile Mbalula has warned protesters to be peaceful, adding that action will be taken against those who threatened to blockade roads with trucks and tractors.
Midvaal Mayor Bongani Baloyi is now on his way to the R59 highway in Vereeniging where farmers are protesting against increasing levels of violence targeted at them.
Baloyi is says he will receive a memorandum from the protesters.
“I think traffic is really bad as it blocked up and it’s not moving too well so people are using alternative routes at this moment. So, people are going to be late at work and this may cause some frustration but we’ll open the road as soon as possible.”
