A massive explosion at a fertilizer plant in West, TX has left over 160 people injured and up to 15 dead. Witness Jason Shelton told DallasNews.com that the explosion was the result of a fire, but when water was sprayed on the ammonia nitrate, the plant "exploded just like the Oklahoma City bomb."  Another witness told  the Waco Tribune that everything within four blocks of the plant was completely destroyed. The U.S. Geological Survey says that the blast was so strong, it registered at a 2.1 on the Richter scale.

The video below captures the explosion from a distance, showing the building burning for about thirty seconds before the explosion hits. Be warned—it's absolutely terrifying:

There are still missing firefighters and civilians who may be trapped inside of a collapsed nursing home. We will update with more information as it becomes available.
