US President Donald Trump has said such threats "have no place in the United States of America".

Law enforcement officials have begun investigating the pipe bombs. There have been reports of suspicious packages also being sent to:

and former CIA Director John O. Brennan.

The latter package was sent via CNN and resulted in the Time Warner Center in Manhattan being evacuated. There was also white powder in the package.

Emergency services used a spherical vessel to transport the suspicious device from the building.

In an email to staff, CNN President Jeff Zucker wrote: “The NYPD has concluded its security sweep, and it is now safe to return to the building. I so appreciate your patience, as I know what a long day this has been for all of you.”

None of the packages exploded and there is still the possibility they are hoax devices.

Trump says “we just have to unify” after leading Democrats were mailed bombs

The FBI’s Joint Terrorist Task Force is investigating the packages.

The bureau has also released a statement saying the bombs are similar to the device removed from the house of billionaire investor and Democratic party donor George Soros on 22 October. Law enforcement officials are trying to determine if the bombs were sent from the same source.

Cuomo has stationed an additional 100 National Guard soldiers to key security locations in New York, including the LaGuardia and John F. Kennedy airports, The Staten Island crossings and major bridges and tunnels.

Trump has been briefed on the issue by the FBI and told reporters at the White House that “the safety of the American people is my highest and absolute priority”.

“In these times we just have to unify. We need to come together and send one very clear unmistakable message that threats or acts of political violence of any kind have no place in America.”

First Lady Melania Trump said “We cannot tolerate those cowardly attacks and I strongly condemn all who choose violence.” Trump’s daughter Ivanka also decried the attacks on Twitter.

Several of the packages listed Wasserman Schultz as the sender.

New York Mayor: “an act of terror”

New York Mayor Bill de Blasio denounced the bombs as “an act of terror attempting to undermine our free press and leaders of this country”.

“To all public officials, to all partisan affiliations – don’t encourage violence, don’t encourage hatred, don’t encourage attacks on media. You can disagree but you have to show respect.”

Trump rallies have often featured the crowd chanting “CNN sucks”.

Cuomo’s Manhattan office also received another suspicious parcel. His spokesperson Rich Azzopardi said a “preliminary investigation” concluded it contained “computer files on the hate group, The Proud Boys, who recently appeared in New York.”
