Authorities in London and in several places here in the U.S. are investigating a series of suspicious packages arriving from Yemen. At least two of the packages were addressed to a Chicago synagogue, but none of the packages were actually explosives. So was this a dry run for a real terrorist strike down the road or could there be plans for an actual attack this weekend? How surprised should we be that this story come just four days before major elections in the U.S.? What does the Yemeni link tell us and how much can the Yemeni government do to stop attacks originating from its country? We ask Dr. Walid Phares from the Foundation for the Defense of Democracies and find out why he’s investigating a possible link between these packages and the recent shootings at military sites in Virginia.
