The leader of Gabon's military junta has vowed to return power to civilians after "free, transparent" elections.
However, in a speech after being sworn in as interim president, he did not give a date for military rule to end.
The coup, that ended more than 50 years of rule by the Bongo family in Gabon, was welcomed by crowds of cheering civilians that turned up at the inauguration.
However, some question his links to the old regime and say Gen Nguema's rule will be a continuation of the Bongo dynasty.
