The alleged New York City attacker has told investigators that he planned on continuing his killing spree, and intended on racking up more victims on the Brooklyn Bridge.

Sayfullo Saipov told law enforcement of his plan after waiving his Miranda rights, according to the FBI, and indicated that he "felt good about what he had done."

The suspect spoke to investigators from his hospital bed, where he is recovering from gunshot wounds he received when a New York Police Department officer shot him near Chambers Street in lower Manhattan.

At least eight people are dead after the attack, in which a pickup truck crashed through people on a bike path that runs alongside the west side of Manhattan. Mr Saipov told investigators that he had chosen to attack on Halloween because he knew that there would be a lot of people on the streets, and that his plan was to kill people on the West Side Highway and then "proceed to the Brooklyn Bridge to strike pedestrians," according to a complaint filed against him.

Gruesome details of Mr Saipov's plans have emerged in the day after the attack, including news that Mr Saipov requested an Isis flag be hung in his hospital room, and that he had numerous videos of violent beheadings on his cell phone.

Just weeks before the Manhattan attack, Mr Saipov had searched "Halloween in NYC" online, and had practised making turns with the rented truck so that he would be familiar with the vehicle.

A neighbour of Mr Saipov, in Peterson, New Jersey, said Wednesday that he had noticed the truck - a white pickup rented from Home Depot - before, and noted that he never saw any construction equipment in the truck bed.

Mr Saipov has been charged with one count of providing material support to a foreign terrorist organization, and one of using a motor vehicle as a weapon. He is currently under guard at a Manhattan hospital.
