Mr Breyten Breytenbach, the Afrikaans writer and poet, was today jailed for nine years by the Pretoria Supreme Court for taking part in "terroristic activities." ...Referring to the public apology which Mr Breytenbach made in court yesterday, the judge said he believed his testimony of regret was genuine. He also took into account that Mr Breytenbach's crime--the formation of an organization known as "Atlas" or "Okhela," whose aim was to overthrow the South African Government--never got beyond the discussion stage. However, violence could have resulted from the poet's actions, he said.
