 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.

Input: Consider Input: Verify if the sentiment of the following document towards the entity Ben Bernanke is Positive . Federal Reserve Chairman Ben Bernanke signaled Thursday that sales of the central bank's holdings in mortgage-backed securities may play a more prominent role in the withdrawal of monetary stimulus than he indicated last month.
 "I anticipate that at some point we will in fact have a gradual sales process " Bernanke said Thursday in testimony to the House Financial Services Committee. In prepared remarks  he avoided repeating a February statement that the Fed won't sell any securities "at least until after policy tightening has gotten under way." Instead  he said Thursday the tool is one way of "applying monetary restraint."
 "We would like to get back to an all-Treasury portfolio within a reasonable amount of time " Bernanke said in response to a question from Rep. Jeb Hensarling  R-Texas. The balance sheet should eventually be reduced to less than $1 trillion  Bernanke told Rep. Ron Paul  R-Texas  who advocates abolishing the Fed.
 Raising the interest rate paid on funds deposited by banks at the Fed  as well as so-called reverse repurchase agreements that temporarily drain cash from the banking system  will still be among the main tools for tightening credit  Bernanke said.
 "The FOMC is not comfortable with holding all of these securities until they mature  as some would be 30 years  and we want to move more quickly than that back to the pre-crisis balance sheet " Bernanke said. The Fed wouldn't sell assets in a "really weak economy " he said.
 At the same time  Bernanke didn't say when the Fed would begin executing its strategy. He said the U.S. economy still needs low interest rates and that the central bank will be ready to tighten credit "at the appropriate time."
 "The economy continues to require the support of accommodative monetary policies " Bernanke said in prepared testimony  repeating parts of a statement to the panel from last month.
 Thursday's hearing  originally scheduled for Feb. 10  was postponed because of a snowstorm. The Fed went ahead and released Bernanke's prepared testimony that day  in part to lay the groundwork for a planned increase in the interest rate the central bank charges for direct loans to banks.
 Responding to questions  Bernanke said the "unemployment situation is very weak " and the housing market is "still quite weak."
