Suspect Behind New York Bombings

Bombings in New York and New Jersey over the weekend as well as the discovery of several unexploded devices have led authorities to believe there may be a terror cell at work in those two states.

And a manhunt is under way for 28-year-old Ahmad Khan Rahami after New York police identified him as wanted in connection with the bombing Saturday night in New York's Chelsea neighborhood, which wounded 29 people.

Earlier Saturday, a garbage can exploded near the starting line of a Marine Corps charity run in Seaside Park, New Jersey.

And on Sunday night, a backpack with multiple bombs inside was found in Elizabeth, New Jersey. As authorities tried to investigate, one of those bombs exploded.

The series of attacks come as New York hosts world leaders at the United Nations General Assembly this week.

Officials want to question Ahmad Khan Rahami because they believe he is the man seen in surveillance videos rolling a duffel bag near the scene of the bombing in New York's Chelsea neighborhood, according to multiple officials.

The FBI described Rahami as a U.S. citizen of Afghan descent with a last known address in Elizabeth, New Jersey, the same city where an explosives-laden backpack was found Sunday night.
