The Burundian President, Domitien Ndayizeye, has formed a new government which includes members of the rebel Forces for the Defence of Democracy.
Pierre Nkurunziza (l) is now minister for good governance
This follows the signing of a peace agreement between the government and the FDD rebels at a regional summit in Tanzania a week ago.
It is seen a key step to ending the civil war which is estimated to have cost 300,000 lives in the past decade.
But fighting continues, as a small rebel group has refused to enter talks.
The inclusion in the new government of the FDD former rebels marks a major step forward in a long running effort to end the Burundi 10-year civil war.
President Ndayizeye named the leader of the FDD, Pierre Nkurunziza, as Minister for Good Governance and appointed three other FDD members to ministerial positions.
40% of army officers
Second assembly vice-president
Assembly deputy secretary general
35% of a new police force
35% of vacant secret service posts
FDD fighters to be demobilised
However, the four have not yet arrived in Burundi and no date has been set for their swearing-in.
They are expected in Bujumbura within days.
The formation of a power sharing government is aimed at ending the war between ethnic Hutu rebels and an army dominated by the Tutsi minority.
But a smaller Hutu rebel group, the extremist Forces for National Liberation, or FNL, has so far refused to negotiate with the government.
The FNL has continued attacks despite an ultimatum from African leaders at last week's peace summit threatening sanctions unless the group enters negotiations within three months.
