The soldiers arrived late Tuesday night  the first sign of a federal government intervention in a city beset by targeted killings by Boko Haram for weeks.
 Zarewa also said police found the unexploded bombs after an alleged Boko Haram bomb attack on a police station in Gamboru  a building destroyed by rioting sect members in July 2009. The rioting  as well as a subsequent security crackdown  left more than 700 people dead.
 Followers of Boko Haram  which means "Western education is sacrilege" in the local Hausa language  went into hiding after the July 2009 riot  as police began arresting anyone caught listening to or holding a sermon by the sect. However  officials now fear the group has rearmed. A video recording released in late June showed a Boko Haram leader calling for new violence as the one-year anniversary of their attack neared.
 Boko Haram has said it wants a stricter version of Islam's Shariah law in place across Nigeria. Nigeria  a nation of 150 million people  is divided between the Christian-dominated south and the Muslim north. A dozen states across Nigeria's north already have Shariah law in place  though the area remains under the control of secular state governments.
