Witnesses who spoke with CBS said the suspect used Molotov cocktails to attack people walking for "Run for Their Lives," a grassroot organization that facilitates global run and walk events calling for the release of Israeli hostages held by Hamas.

Police initially evacuated three surrounding blocks and expanded the evacuation area just before 5:15 p.m.
