Authorities say suspected members of a radical Muslim sect detonated a bomb outside a late governor's house in Nigeria's restive northeast.
Col. Victor Ebhaleme said Wednesday that Tuesday night's blast outside the home of the former Borno state governor Mala Kachalla did not hurt anyone. Kachalla died in 2007, but his family still resides at the house in Maiduguri.
The military blames a sect locally known as Boko Haram. The group has claimed responsibility for a series of bombings in northern Nigeria.
In a June 12 leaflet attributed to Boko Haram, the group asked for the prosecution of some former governors which it blamed for the 2009 death of its leader. The source of the leaflet could not be verified.
Three northern governors who were in office in 2009 recently published apologies to the group in a local paper.
