A \"locally made\" bomb was exploded at Bolak El-Dakror police station in Giza Province by unknowns on Saturday, with no casualties mentioned, Egypt\'s interior ministry said. A source at the ministry said in a statement to the Middle East News Agency that explosives experts went to the scene in order to check the location and the bomb components.
