Authorities in southeastern Nigeria have imposed a curfew following clashes between police and a separatist group.
The governor of Anambra state announced the curfew on Sunday in a televised address and added that soldiers will be deployed in the market city of Onitsha to stop four days of violence.
A police raid Thursday led to clashes with the separatist group known as "MASSOB" (Movement for the Actualization of the Sovereign State of Biafra). At least six people were killed.
MASSOB emerged in the early 1990s to campaign for the peaceful secession of southeastern Nigeria, a region dominated by the ethnic Ibo group. The group's leader, Ralph Uwazuruike is in jail facing treason charges.
