An explosion rocked New York City’s Chelsea neighborhood, injuring 29 people. Officials are not saying at this time whether the incident was terror-related.

CNN reports:

Police are hunting for answers on what caused an explosion that injured 29 people in New York’s Chelsea neighborhood, shortly before a second suspicious device was found nearby.

New York City Mayor Bill de Blasio told reporters early indications are that the explosion at 23rd Street and 6th Avenue in Manhattan at about 8.30 p.m. Saturday “was an intentional act.”

But, he said, “there’s no specific and credible threat against New York City at this time from any terror organization.”

Investigators believe the blast was caused by an explosive device in or near a dumpster, a law enforcement source told CNN.

They are looking at surveillance video that appears to show a person near where the explosion occurred, in an attempt to determine if that individual is connected to the blast.

Watch the report:

The second device found nearby  is reported to have been fashioned with a pressure cooker (the same type of device used in the Boston marathon bombing in 2013).  It was removed without incident by the NYPD Bomb Squad.

USA Today reports:

Authorities removed a second explosive device early Sunday — reportedly a pressure cooker — near the site of Saturday night’s blast that injured more than two dozen people in the Chelsea neighborhood.

. . . .  A device believed to be a pressure cooker was subsequently found on West 27th Street, four blocks from the initial blast on West 23rd, according to the New York Police Department. “The suspicious device on West 27 Street in Chelsea has been safely removed by the NYPD Bomb Squad,” the police department tweeted at 2:24 a.m. ET Sunday.
