Conde narrowly escaped two armed assaults on his residence on Tuesday which killed three people and has sought to reassure investors that he is fully in control of the turbulent West African country.

The assaults raised concerns about the country's progress towards drawing a line under unstable leadership that is prone to coups, and make the most of its place as the world's top exporter of aluminum ore bauxite.

A former army chief sacked by Conde in December and at least one former presidential guard member were arrested hours after the attack, but police and presidency sources said 70 others have also been detained.
