Scattered gunfire and explosions shook France on Thursday as its frightened yet defiant citizens held a day of mourning for 12 people slain, including Wolinski and Cabut, at a Paris newspaper. French police hunted down the two heavily armed brothers suspected in the massacre to make sure they don't strike again.(AP Photo/Francois Mori)
