Robert Spencer’s Jihadwatch.org site had this:
Rainbow bridge, on the Canadian side. as stated earlier, and Iranian passport was found near the vehicle according to Fox News
Iranian passport reportedly found near car that exploded at US-Canada border
This whole story wreaks of possible lies and maybe hidden or untold pieces of information.
Numerous inconsistencies:they thought they found a piece of possible explosive matter but authorities say it wasn't that,passport suggested but not found,car explodes in mid air,no explanation, car is blown into oblivion by explosion with massive debris field with no explanation at all. Too much here that makes little sense.
Also, story lacks a lot of hard evidence which is perfect for anyone trying to hide the truth.
Hard to say what happened here.
