ABC News has obtained never-before-seen images of the IEDs found after the suspect accused in the New Orleans truck-ramming attack was killed in a shootout with police.

The suspect in the New Orleans New Year's Day terrorist attack failed to detonate two improvised explosive devices he had planted along the city's famed French Quarter prior to ramming his truck into a crowd.

New evidence shows the attack in New Orleans could have been even more deadly, as Shamsud-Din Jabbar was seen placing improvised explosive devices around Bourbon Street. They are also investigating trips Jabbar took to Egypt and Canada and two previous visits to New Orleans.
