Investigators seek cause of Texas blast that killed at least 14

WEST, Texas (Reuters) - Investigators sifted through debris on Friday to determine the cause of a Texas fertilizer plant explosion that obliterated parts of a small town and killed at least 14 people, including volunteer firefighters who had raced to the scene in advance to douse a blaze.

There was no indication of foul play in the fire or the blast it triggered Wednesday night at West Fertilizer Co, a privately owned retail facility that was last inspected two years ago, authorities said.
