Survivors and family members of those who died in the bombing of the Oklahoma City federal building will gather to commemorate the 15th anniversary of the attack.
Authorities expect hundreds of people to attend Monday's ceremony at the Oklahoma City National Memorial to remember the 168 people killed in the April 19, 1995, explosion. More than 600 others were injured in the attack at the Alfred P. Murrah Federal Building.
U.S. Department of Homeland Security Secretary Janet Napolitano will speak during the ceremony scheduled to begin shortly before 9:02 a.m. - the time that the bomb detonated in 1995.
Attendees will remember the dead with 168 seconds of silence.
