Demonstrators are blocking motorways in the South African cities of Cape Town and Johannesburg in protest at the murder of white farmers.<\/p>\n
People have been posting their pictures on Instagram:<\/p>\n
The BBC’s Pumza Fihlani in Johannesburg says the protests are already causing racial divisions after some demonstrators were seen carrying the old apartheid flag.<\/p>\n
It comes three days after\u00a0two white farmers were sentenced to more than 10 years in prison each for forcing a black man into a coffin. They intend to appeal against the sentence.<\/p>\n
Those behind the protests have urged people to wear black:<\/p>\n
While most photos appear to show only white protestors, some show a racial mix:<\/p>\n
