Racial tensions between black farm workers and their commonly white employers have heightened in South Africa since the murder of Eugene Terreblanche - the white supremacist leader - in the country's northwest.

Two black farm workers, who were employees of Terreblanche, have been accused of murdering him over unpaid wages.

Many white farmers say they are being targeted in "increasing racially motivated" attacks.

Meanwhile, black workers say they are mistreated and exploited by their white employers who are "stuck in the apartheid mentality".
