New York City Police confirmed a Home Depot rental van drove onto a pedestrian and cycle path alongside the West Side Highway at full speed, hitting several people.
The truck then hit a school bus, which was carrying two adults and two children.
4 News reported the driver then allegedly screamed ‘Allahu Akbar’ and got out of the vehicle. This has not been confirmed by authorities, although the NYPD commissioner said the statement made by the attacker when he exited the vehicle was “consistent” with a terrorist attack.
He was armed with two weapons and began running before being shot by police. The weapons later turned out to be imitation firearms.
US media named him as Sayfullo Saipov, a Florida resident who came to the US in 2010.
New York City Mayor Bill de Blasio described the attack “cowardly act of terror aimed at innocent civilians”.

Witnesses reported hearing gunshots near Stuyvesant High School, a top-ranked public New York City school, at around 3pm local time on Tuesday afternoon which were later revealed to be from a uniformed police officer as he took down the attacker.
Bodies were pictured lying on the ground outside the school in what police are now treating as a terror attack.
He later followed the tweet with: “We must not allow ISIS to return, or enter, our country after defeating them in the Middle East and elsewhere. Enough!”
It is not yet clear whether the attacker had any links to Islamic State.
He then added: “My thoughts, condolences and prayers to the victims and families of the New York City terrorist attack. God and your country are with you!”
In the UK, Prime Minister Theresa May said she is “appalled by this cowardly attack” in New York City and “my thoughts are with all affected.”
New York Mayor Bill de Blasio said it was a tragedy of “the greatest magnitude”.

He told reporters: “The is a very painful day in our city.
“This was an act of terror, a particularly cowardly act of terror aimed at innocent civilians.
“We know that this action was intended to break our spirit. But we also know that New Yorkers are strong, New Yorkers are resilient and our spirit will never be moved by an act of violence and an act meant to intimidate us.”
He called on the public to be vigilant as he revealed more officers would be on New York streets in the coming days.
The mayor added: “I want to ask all New Yorkers and all Americans to keep the families of all those lost in your prayers.”
New York Police Commissioner James O’Neill confirmed a 29-year-old male got out of the vehicle after driving the wrong way down the bicycle path and ploughing into several people before coming to a halt after striking the school bus.
He was brandishing two handguns and an officer at the scene “shot him in the abdomen”.
The guns were later revealed to be a “paintball gun and a pellet gun”.
New York Governor Cuomo added there is no evidence to suggest there is a wider plot, hinting this could be a lone wolf-style attack.
The counter-terror unit urged people to avoid the West Side Highway area while they deal with the incident.
The FBI has joined the New York City Police Department in investigating the incident and President Trump has been briefed.
The attacker was left injured in the incident and has been taken into custody. His injuries are not thought to be life-threatening.
John Williams, a 22-year-old student, told reporters at the scene that he heard about five gunshots before seeing a large man with curly being taken into custody.
