Three suicide bombers drove a stolen black SUV toward a Joint Task Force headquarters , but could not get through the gate , military spokesman Lt. Col. Hassan Mohammed said . The blast damaged roofs and walls of the base . Mohammed said two other simultaneous explosions took place at other military facilities . An unspecified number of Nigerian soldiers suffered injuries . Saturday evening , a suicide bomber launched another attack in Maiduguri , Mohammed said . No casualties were reported except for the bomber . He blamed the militant group Boko Haram for the attacks . Loosely translated , the group 's name means `` Western education is sinful . '' It wants to establish a state based on Sharia , or Islamic law , in northern Nigeria . The Red Cross official said Boko Haram is suspected in the Damaturu attack as well .
