Guinea-Bissau situation concerns Pillay - UPI.com HARARE, Zimbabwe, May 25 (UPI) -- Anyone tied to violent repression of human rights in Guinea-Bissau following the April 12 coup must be held accountable, the top U.N. rights commissioner said. Military forces that toppled the government in Guinea-Bissau in April returned power to civilian authorities this week and agreed to organize elections within a year. U.N. High Commissioner for Human Rights Navi Pillay expressed concern about instability in the country despite the political developments. "Anyone who has committed violent or excessive acts must be held accountable," she said in a statement. I cannot stress enough the importance of full respect for the fundamental human rights of freedom of movement and expression, as well as peaceful association and assembly, Pillay went on to express concern about a list allegedly circulated by military authorities containing the names of 57 people banned from leaving the country. Such restrictions, she said, could be in violation of international political rights. None of Guinea-Bissau's elected leaders has finished a term in office since the country gained independence from Portugal in the 1970s. Pillay issued her statement from Zimbabwe, where she met with longtime President Robert Mugabe.
