Mass Shooting in Colorado; Conflict Intensifies in Syria

At least 12 people are dead and 38 wounded after a shooting this morning in Aurora, Colorado, a suburb of Denver. We hear witnesses describe the scene, which has already set off debate about America's epidemic of gun violence. Also, international efforts to end Syria's civil war have reached a standstill, and tens of thousands are fleeing the country as fighting escalates from Damascus to international borders.
