Homeland Security Secretary Janet Napolitano says Oklahoma City's spirit in the wake of the bombing of the Alfred P. Murrah Federal Building 15 years ago serves as an
example to the nation.
Napolitano also warned of the need for continued vigilance against terrorists when she spoke today to survivors and victims' relatives during a 90-minute memorial to the 168 lives lost in the tragedy.
Some dabbed away tears as the anniversary ceremony closed with family members reading a roll call of those who died. Across Oklahoma City, people observed 168 seconds of silence to honor the dead.
The ceremony followed a time-honored script. Shortly before 9:02 a.m. -- when the bombing occurred -- bells tolled in downtown Oklahoma City. Some family members visited the site of the federal building razed in the attack and left ribbons, wreaths and other objects on chairs that stand on the site to honor the dead.
