At least eight people were injured Saturday in Modena, Italy when a crazed driver rammed his car into a crowd at full speed — and then knifed a hero who stopped him when he tried to flee following his cowardly act. The man has been identified by authorities as Salim el Koudri, a 31-year-old Italian citizen of Moroccan origin. The motive is not yet known, but a terrorist attack is not being ruled out, Italian newspaper La Pressa reported.
