The series of parcel bombs in Texas that have killed two people and put residents on edge escalated on Tuesday with two more incidents, a bomb that exploded at a FedEx distribution center near San Antonio and one that was discovered before it detonated.
A third explosion Tuesday evening in Austin was not a package bomb, and officials said it did not appear to be related to the other incidents.
The latest cluster of booby-trapped packages brought to six the number of explosive devices — five that detonated — that have come under investigation in Texas this month as the work of a possible serial bomber.
