JOHANNESBURG - Western Cape police are investigating cases of arson and malicious damage to property after two freight trucks were attacked and torched.
They were carrying products bound for a grocery store.
The incident led to the closure of the N1 highway near Paarl.
There have been several attacks on heavy-duty trucks since Tuesday.
Three vehicles were set alight.
Others were hijacked on the N7 and N2 highways near Somerset West and used to block major routes in the province.
The Truckers' Association of South Africa has condemned the attacks.
It's calling on drivers to put a stop to this.
“We don’t condone violence and we really don’t agree with the torching of trucks, because their protest it was not valid because they were given a court interdict... we will be having meeting with them in few days, so that we can resolve the issue,” said Tasa president Mary Phadi.
Law enforcement agencies have been deployed to patrol all highways to make sure there is a free flow of traffic.
