Another Attack Discovered at an Electricity Substation Near the Border — and One Congressman Says It’s ‘Only a Matter of Time’ Before More Attackers ‘Exploit This Vulnerability’

A 50,000 gallon diesel fuel tank at a critical transformer substation south of Tucson near a border town that has been the center of immigration news lately was the target of an attack last week, but the make-shift bomb failed to cause a major explosion or power outage.

More than 30,000 Arizona residents could have been stripped of all access to power for their homes and businesses, for an unknown period of time, if the explosive device had knocked out their critical transformer substation.

Instead, the device — roughly described by local police as a homespun device that could fit in the palm of your hand — failed to ignite the diesel fuel in one of the storage tanks for four back-up power generators housed at the site.
