SourceQUOTE said:Mr Terreblanche, 69, was beaten to death by two farm workers after a dispute over unpaid wages, police say. Two people have been charged.
President Jacob Zuma has appealed for calm, saying the killing should not incite racial hatred.
Mr Terreblanche, who campaigned for a separate white homeland, came to prominence in the early 1980s.
The murder comes amid growing anxiety about crime in South Africa and what opposition politicians say are irresponsible and racially inflammatory sentiments from a minority of the ruling ANC party, says the BBC's Karen Allen in Johannesburg.
The incident comes 10 weeks before South Africa hosts the first World Cup football tournament on African soil.
A spokesman for Mr Terreblanche's Afrikaner Weerstandsbeweging (Afrikaner Resistance Movement - AWB) linked the killing to the recent singing of an apartheid-era song by a firebrand ANC leader.
