UPDATE: At least ten people were killed and over a dozen injured when a suicide bomber blew himself up at the Borno state Police commnad headquarters in Maiduguri, as earlier reported today by SaharaReporters.
Hours earlier, a suspected bomber died when an explosive went off prematurely in another part of the city, prompting the Nigerian Red Cross to warn that conditions in the city were getting worse.
Earlier report: A suicide bomber struck the police headquarters in Maiduguri around mid day today. Eyewitness told Saharareporters that the attacker drove a car bomb directly into the headquarters, sources said the car exploded at the gate of the Borno State police command on Damaturu road directly opposite Govt Secondary school in Maiduguri.
The car was unable to gain access into the premises because of the protective security bar at the gate and the car exploded there killing the bomber and two policemen, according to eyewitnesses.
The police have cordoned off all access routes to the headquarters, creating a massive traffic jam within the city. Traders have halted business activities, and residents have fled to take refuge in their various houses in the ensuing tension that followed the attack.
