<br/>Maoists blew up a school building at Sohar village in Chatra district of Jharkhand alleging that it was being used as a make-shift camp by security personnel. Police said today that the three-room school building, blasted by the Maoists was razed last light. <br/><br/>Claiming responsibility for the blast in a poster left behind, CPI (Maoist) said the school was blasted as the police had used it as their shelter during the November-December Assembly elections.
