JOHANNESBURG (AFP) - Desmond Tutu is now seen as South Africa's moral compass, but in the 1980s he was reviled by the whites' government and criticised within the liberation movement, a new biography said Sunday. Excerpts from "Tutu: The Authorised Portrait" published in The Sunday Independent captured some of his most difficult moments in the 1980s at the forefront of the fight against the segregationist government. His support for international sanctions on the regime drew outrage from the authorities, who retaliated by bombing the building housing the South African Council of Churches in downtown Johannesburg. The night-time blast in August 1988 destroyed Khotso House, meaning "House of Peace", but caused no injuries. Tutu was also the target of death threats and a smear campaign, in which apartheid security forces hanged a monkey foetus outside his home, in an attempt to convince township residents that he was under a witch's spell, the book said.
