It appears that the only thing that saved lives in a massive, multi-state, coordinated terror attack was the terrorists’ own incompetence.

New York police say they’re looking for 28-year-old Ahmad Khan Rahami in connection with the Chelsea bombing over the weekend.

The intense investigation into the weekend bomb blasts in New York and New Jersey is leading authorities to signs of a possible terror cell in those two states, law enforcement officials told CNN Monday.

The ongoing investigation, which includes two bombs in New York City and devices in two cities in New Jersey, has given authorities leads on specific people who are urgently being sought.

Also on Monday morning, a federal law enforcement official said BBs and ball bearings were among the pieces of metal that appeared to be packed into both pressure cooker bombs in New York.

One of those devices exploded on 23rd Street, but the fact that it was partly under a metal trash container may have diminished the force of the blast.

The latest developments came just hours after a backpack containing multiple bombs was found Sunday night near an Elizabeth, New Jersey, train station, according to the FBI and the city’s mayor.
