US President Donald Trump has ordered the Department of Homeland Security to "step up" inspection measures, after a tedious truck-terror attack in New York.

Eight people were taken life and 11 hurt when the driver of the truck hit people on a cycle path in Lower Manhattan in which Five Argentines were among the dead.A 29-year-old man was shot by police as he left the car, and under arrest. Media named him as Sayfullo Saipov, an Uzbek migrant who came to the US in 2010.

The suspect is now in a hospital as police shot in his belly. A note was found in the truck that read to so-called Islamic State, law enforcement sources were quoted as saying by US media.

Sayfullo Saipov had been arrested in Missouri last year over a traffic fine.

President Trump had been concussed about what happened in New York on Tuesday afternoon, the White House asserted.

"In NYC, looks like another attack by a very sick and deranged person. Law enforcement is following this closely. NOT IN THE U.S.A.!"

"We must not allow ISIS [Islamic State] to return, or enter, our country after defeating them in the Middle East and elsewhere. Enough!"

"My thoughts, condolences and prayers to the victims and families of the New York City terrorist attack. God and your country are with you!"

Trump also declared that he had ordered the Extreme inspection Program to be stepped up. He did not detail further.
