Hillary Clinton appeared to criticize her rival Donald Trump on Saturday night for immediately referring to the New York City blast as a bombing, only moments before calling it a bombing herself.

Her comments came not long after an explosion rocked Manhattan's Chelsea neighborhood, injuring 29 people, damaging neighboring buildings and shattering glass and sending shrapnel flying across the street.

After landing in White Plains, New York, a noticeably tired-looking Clinton told reporters she had been 'briefed about the bombings in New York and New Jersey and the attacks in Minnesota.'

A reporter then asked what she thought about the Republican presidential nominee appearing to preempt New York City officials when he declared a 'bomb went off' in New York City before officials had released details.

'Secretary, do you have any reaction to the fact that Donald Trump immediately took the stage tonight, calling the explosion a 'bomb',' the reporter asked.

'Well I think it's important to know all of the facts about an incident like this,' Clinton said.

'That's why it's critical to support the first responders, the investigators who are looking into it, trying to figure out what did happen.

She added: 'I think it's always wiser to wait to until you have information for making conclusions, because we are just in the beginning stages of trying to determine what happened.'

The Democratic presidential nominee had been briefed on the incidents shortly after her speech to the Congressional Black Caucus Foundation dinner in Washington, D.C. on Saturday night.

In her remarks to media, she sought to present a more cautious response, underscoring the difference between the two candidates' styles.

She said, 'we need to do everything we can to support our first responders — also to pray for the victims. We have to let this investigation unfold.'

Clinton was referring to a pipe bomb that exploded in a New Jersey shore town and reports of a shooting and a stabbing at a Minnesota mall.

'We've been in touch with various officials including in the mayor's office in New York to learn what they are discovering as they conduct this investigation and I'll have more to say about it when we actually have the facts,' she said.

Her remarks came after Trump made comments on the explosion minutes after stepping of his plane during a rally at an airport hangar in Colorado Springs, Colorado.

'I must tell you that just before I got off the plane a bomb went off in New York and nobody knows what's going on,' Trump said on Saturday.

He continued: 'But boy we are living in a time - we better get very tough, folks.

'We better get very, very tough. It's a terrible thing that's going on in our world, in our country and we are going to get tough and smart and vigilant.'

The Republican presidential nominee made the comments around 9.10pm, shortly after the explosion as emergency officials were responding to the blast.

A spokeswoman for Trump did not respond to an email asking whether Trump was briefed about the incident before taking the stage.

Officials in New York and New Jersey said Sunday they were still investigating who was behind the explosions and what the motivation was, while the Minnesota attack was being investigated as a possible act of terrorism.

On Sunday, Clinton condemned what she described as 'apparent terrorist attacks' in Minnesota, New Jersey and New York.

She stressed that investigations were still underway, saying: 'Law enforcement officials are working to identify who was behind the attacks in New York and New Jersey and we should give them the support they need to finish the job and bring those responsible to justice — we will not rest until that happens.'

On the attack in St. Cloud, Minnesota, the former secretary of state noted that the Islamic State group had claimed responsibility and added, 'This should steel our resolve to protect our country and defeat ISIS and other terrorist groups.'
