Ammonia Leak and Explosion in Mexico Claims 7 Lives

Seven people are dead after an ammonia pipeline was struck open and exploded.

Another forty-three were injured, either in the blast or from inhaling the ammonia.

According to authorities, a construction crew accidentally struck the pipeline carrying the ammonia to a petrochemical plant.

Twelve hundred residents were evacuated from the surrounding area.

Pemex, which runs the pipeline, is unclear when the area will be completely cleaned up.
