A senior United Nations official says planned November elections in the tiny West African nation of Guinea-Bissau can't be seen as free and fair unless progress is made on investigations of recent high-profile political killings. Ivan Simonovic, the U.N.'s assistant secretary-general for human rights, made his remarks in an interview Wednesday during the U.N.'s first ever high-level human rights mission to Guinea-Bissau, which has been trapped in a cycle of instability since gaining independence from Portugal in 1974.
