Bush honors Israeli professor killed in Virginia Tech shooting

US President George W. Bush on Wednesday honored Professor Liviu Librescu, a Holocaust survivor who died trying to keep a gunman from shooting his students in a killing spree at Virginia Tech University.

''We take strength from his example,'' said Bush during a speech at the US Holocaust Museum to a crowd that included many survivors. Librescu, an aeronautics engineer and teacher at the school for 20 years, saved the lives of several students by using his body to barricade a classroom door before he was gunned down in Monday's massacre.
