NEW YORK (CBSNewYork/AP) — Mayor Bill de Blasio said authorities believe an explosion in Chelsea that left more than two dozen people hurt was “an intentional act” as police investigate a possible secondary device a few blocks from the scene.

Sources told CBS2 that the possible second device found on West 27th Street between Sixth and Seventh Avenues is a pressure cooker with a cell phone and wires attached found in a plastic bag.

The exact cause of the blast on West 23rd Street, which happened at about 8:30 p.m. Saturday, has not been determined, but officials said they don’t believe natural gas was responsible.

“Tonight, New York City experienced a very bad incident,” de Blasio said at a news conference near the scene. “We have no credible and specific threat at this moment.”

De Blasio also said there was no evidence yet that the explosion was connected to terrorism.

“I want to assure all New Yorkers that the NYPD and all other agencies are at full alert, and that our anti-terror capacity in particular is at full alert,” de Blasio said at a late night news conference.

Fire Commissioner Daniel Nigro said a total of 29 people were injured in the blast. He said one person’s injuries were serious and the rest were minor.

Bellevue Hospital Center reported it treated nine patients, none of whom had life-threatening injuries.

Police Commissioner James O’Neill said officers are investigating a possible second explosive device a few blocks away from the explosion on 27th Street between Sixth and Seventh Avenues.

Police sources told CBS2 the second device was a pressure cooker with a cellphone and wires attached, and was found in a plastic bag.

The second device did not detonate. The NYPD Bomb Squad was working to contain and disarm the device, sources said.

It was not clear if the second device was viable or had explosive capabilities, sources said.

City Councilman Cory Johnson said the area of the blast would have been busy on a Saturday night. Witnesses said the explosion blew out the windows of businesses in the area.

“This is a very dense area, the whole block is restaurants and residences and this area on a warm Saturday night is an area swarming with people,” Johnson told 1010 WINS.

Roselyn Olivares, who lives on 23rd Street between Sixth and Seventh avenues, said the blast did damage to her fourth floor apartment.

“My bedroom window was blown out,” she told 1010 WINS. “We didn’t know what it was.”

The White House said President Barack Obama has been briefed of the explosion and will be updated as additional information becomes available.

The MTA says 1 and 2 subway trains are not running between Chambers and 34th Street due to the police activity on 23rd Street.

Officials say drivers should also expect extensive traffic delays and street closures in the area. Early Sunday, authorities said all crosstown traffic headed east and west is closed from 14th Street to 32nd Street between Fifth and Eighth avenues. The closures are in effect until further notice.

The blast came hours after a device exploded in Seaside Park, New Jersey Saturday morning, shortly before thousands of runners participated in a charity 5K race to benefit Marines and sailors.

De Blasio said at this point, there is no indication that the two incidents are connected.

    This is all staged by Donald Trump supporters to make gin up his xenophobic followers and make them believe that Islam is our enemy.

    1. TroyGale says:

      Carl, only the most ill informed would believe that Islam isn’t our enemy. You really need to read your history…in 1899 Winston Churchill said:
      “How dreadful are the curses which Mohammedanism lays on its votaries!
      Besides the fanatical frenzy, which is as dangerous in a man as hydrophobia
      in a dog, there is this fearful fatalistic apathy. The effects are apparent in many
      countries. Improvident habits, slovenly systems of agriculture, sluggish methods
      of commerce, and insecurity of property exist wherever the followers of the Prophet
      rule or live. A degraded sensualism deprives this life of its grace and refinement; the
      next of its dignity and sanctity.

      The fact that in Mohammedan law every woman must belong to some man as
      his absolute property, either as a child, a wife, or a concubine, must
      delay the final extinction of slavery until the faith of Islam has ceased
      to be a great power among men. Individual Moslems may show splendid
      qualities – but the influence of the religion paralyses the social
      development of those who follow it. No stronger retrograde force exists
      in the world. Far from being moribund, Mohammedanism is a militant and
      proselytizing faith. It has already spread throughout Central Africa,
      raising fearless warriors at every step; and were it not that Christianity
      is sheltered in the strong arms of science, the science against which it
      had vainly struggled, the civilization of modern Europe might fall, as fell
      the civilization of ancient Rome.”

      Wake up! It isn’t being a xenophobe to want to protect your fellow citizens from harm. It is called love of your fellow citizens, and nation.

      Islam does a fine job of that all on their own.

  4. JMWinPR says:

    Were there any signs declaring this an IED Free Zone? If not, Mayor Bill should be brought up on charges for failure to uphold the inanities of his orifice.

  5. David Stern says:

    Well New York’s mayor would not tell the truth as to whether it was terrorist or not. Why? Because he wants Hillary elected

  6. Benjamin Eaton says:

    Since when is any bomb set off in a public place NOT terrorism? To say it’s not implies some bombs that kill, maim and cripple are somehow justified as public protest. de Blasio is an id10t.

  7. Dave says:

    Muslims are the enemy of FREE People everywhere.
    Past time to start the world wide purge of these subhumans.

  8. Jerry Seinfeld says:

    Here’s a great idea: Let’s import more “refugees” from Terror-supporting countries.
    What could possible go wrong?
    Or as Hillary (who promised to increase the refugee count by 500%) would say: What difference does it make?

  9. Jerry Seinfeld says:

    “Intentional Act?”
    No $hit, Sherlock!

  10. Sporttster says:

    It was intentional, there were two devices….but they don’t believe it’s terror related…… Can you say ‘spin the H out of this story’?? I sure can…..it is probably linked to a refugee so they do not want it reported, per Obaba.

  11. Max Headroom says:

    Catch the wave!

  12. Airborne869 says:

    Tensions rise in AMERICA as MUSLIMS set off bombs..

  13. Terrorists will change nothing.
    This act will change nothing.
    Life goes on.
    Nothing stops freedom.
    Live on.

    DiBlazio caused this

  15. Jc3 says:

    This is just a taste of a Hillary “presidency”. Death, destruction, mayhem is what she brings. I hope she drops dead before she can kill us all.

  16. Shlomo Schekelstein says:

    It’s a religion of pieces!

  17. ellen says:

    why did it take CBS2News till 11 pm tonight to report this on tv??? insane. No wonder people get their news from the internet

  18. Chris Christie's Belt says:

    The world is gearing up for WW3 if Trumpler gets elected.
    Don’t worry his kids will be safe, they have a doctors note for a bad foot like he had to get out of the draft. Right after he played 2 sports in college and before he forgot what foot it was in an interview.

    1. Lockherup says:

      you had no problem championing hillarys husband , the draft dodger. so move on..nothing to see here

    2. Roy says:

      Libs really digging deep to dream up dirt on Trump, for us, dirt on Hillary is easy. President Trump will take the kid gloves off dealing with terrorists.

      1. Concerned American says:

        The more Trump talks, the more terrorists will make hte USA a target. He will; make things 100 times worse, not better.

        1. Mike says:

          Channeling Neville Chamberlain again?

        2. TroyGale says:

          I note that someone already noted your passive response as similiar to Neville Chamberlain. They are right. You can’t defeat this type of aggression with words, and acting like a coward. For centuries Muslims have not changed one bit, other than learning how to make bombs. Only people with their heads in the sand believe otherwise.

    I bet these NYPD parasites will use this as an excuse to create dumpster brigades!
