How the Texas plant explosion unfolded

Rescue workers continue searching for survivors among the rubble after an explosion devastated West, Texas. The small town which is about 20 miles north of Waco was almost leveled by a massive explosion at a fertilizer plant.

The blast, which was captured on cell phone video could be felt as far as 50 miles away and flattened or damaged dozens of homes. Some reports say more than 5 people are believed to be dead and more than 160 injured.

The investigation is being treated as a crime scene, although there is no proof it is anything more than an accident.
