Guineans hope to finally elect a civilian president on Sunday in a run-off race that has pitted two ethnic groups against each other.

A year after the massacre of 157 in Conakry, no army official suspected of taking part in the killings has been brought before a court in Guinea.

International condemnation mounted on Tuesday after security forces in Guinea shot dead at least 87 protesters.

Former president Lansana Conte was to be buried on Friday as Guinea adjusted to the rule of the military junta that has seized control.
