NEW YORK - Federal prosecutors brought terrorism charges Wednesday against the Uzbek immigrant accused in the truck rampage that left eight people dead, saying he was spurred to attack by the Islamic State group's online calls to action and picked Halloween because he figured streets would be extra crowded.

Even as he lay wounded in the hospital from police gunfire, Sayfullo Saipov asked to display the Islamic State group's flag in his room and said "he felt good about what he had done", prosecutors said in court papers.

Saipov, 29, was brought to court in a wheelchair to face charges that could bring the death penalty. Handcuffed and with his legs shackled, Saipov nodded his head repeatedly as he was read his rights in a brief court proceeding that he followed through a Russian interpreter. He was ordered held without bail.

Outside court, his appointed lawyer, David Patton, said he hoped "everyone lets the judicial process play out".

"I promise you that how we treat Mr. Saipov in this judicial process will say a lot more about us than it will say about him," Patton said.

Meanwhile, the FBI was questioning a second person from Uzbekistan, 32-year-old Mukhammadzoir Kadirov. A law enforcement official said Kadirov was a friend of Saipov's and may not have any role in the case. The official wasn't authorized to speak publicly and spoke to The Associated Press on condition of anonymity.

Prosecutors said Saipov had 90 videos and 3,800 photos on one of his two cellphones,

many of them ISIS-related pieces of propaganda, including images of prisoners being beheaded, shot or run over by a tank.

Saipov left behind knives and a note, in Arabic and English, which included Islamic religious references and said, "Islamic Supplication. It will endure," FBI agent Amber Tyree said in court papers. "It will endure" commonly refers to ISIS, Tyree said.

Questioned in his hospital bed, Saipov said he was inspired by ISIS videos and began plotting an attack a year ago, deciding to use a truck two months ago, Tyree said.

During the last few weeks, Saipov searched the internet for information on Halloween in New York City and for truck rentals, the agent said. Saipov even rented a truck on Oct 22 to practice making turns, and he initially hoped to get from the bike path across lower Manhattan to hit more pedestrians on the Brooklyn Bridge, Tyree said.

He even considered displaying ISIS flags on the truck during the attack but decided it would draw too much attention, authorities said.

John Miller, deputy New York police commissioner for intelligence, said Saipov "appears to have followed, almost exactly to a T, the instructions that ISIS has put out".

In the past few years, the Islamic State has exhorted followers online to use vehicles, knives or other close-at-hand means of killing people in their home countries. England, France and Germany all have seen deadly vehicle attacks.

A November 2016 issue of the group's online magazine detailed features that an attack truck or van should have, suggested renting such a vehicle, and recommended targeting crowded streets and outdoor gatherings, according to the SITE Intelligence Group, a militant-monitoring agency.

US President Donald Trump called Wednesday for eliminating the 1990s visa lottery program that Saipov used to come to the US in 2010, and the Republican president said he would consider sending Saipov to the Guantanamo Bay detention center - an idea the White House reinforced by saying it considered Saipov to be an "enemy combatant".
