The report, released Wednesday by the independent non-governmental organization, says years of conflict between Burundi's ruling National Council for the Defense of Democracy-Forces for the Defense of Democracy Party and opposition parties have resulted in a political standstill that threatens the stability of the country, Crisis Group reported.

The report, "Burundi: Restarting Political Dialogue," suggests that Burundi President Pierre Nkurunziza's unilateral running of the country has led to heightened tensions in the Burundi National Assembly. Crisis Group officials say that with the absence of constructive dialogue over issues concerning disarmament and integration of former rebels into society, opposition groups could further radicalize.

"The NCDD-FDD's authoritarian tendencies are pushing opposition parties toward radicalization," Daniela Kroslak, Crisis Group Africa program deputy director, said in a statement.

"They could be tempted to pursue alliances with the Palipehutu-FNL (Party for the Liberation of the Hutu People) during the next election, which could lead to a renewed ethnic tone to political discourse."
