The search for survivors at a fertilizer plant near Waco, Texas, continued Thursday following a massive blast that killed as many as five and injured 160. The blast, which erupted around 8 p.m., was allegedly triggered by a fire at the plant. After conducting door-to-door searches in the area early Thursday, rescue workers turned to the rubble itself to search for survivors. Experts worry that flames still smoldering in the leveled plant may set off further explosions as well as the emission of hazardous gases into the town, roughly half of which was evacuated overnight. A spokesman for the Texas Public Department of Safety said the damage was comparable to the 1995 bombing in Oklahoma City.
