Remember that previous to 9/11 the worst act of terror on U.S. soil was from a right wing extremist.
A package left at a clinic that performs abortions contained an explosive device that investigators said Thursday could have been deadly.
The incident came just days after a national abortion group alerted providers around the country to an increased risk of violence.
The device, found in a duffle bag Wednesday, "was configured in such a way to cause serious bodily injury or death," said David Carter, assistant chief of the Austin Police Department.
The bomb, which was found in the parking lot of the Austin Women's Health Center, comes on the heels of last week's U.S. Supreme Court ruling which banned a controversial type of abortion and was viewed as an anti-abortion victory.
