Lisbon  - Guinea-Bissau's interim President Raimundo Pereira praised slain president Joao Bernardo "Nino" Vieira as having represented "humanist values," condemning his killing as an "affront to the republic" at a state funeral for Vieira on Tuesday.

The 69-year-old president was shot dead in his home a week ago by soldiers angered by the killing of army chief Tagme Na Wai, Vieira's long-time rival, a few hours earlier. Tagme was buried over the week- end.
