(CNN) -- [Breaking news update, published at 5:35 p.m. ET]
Sayfullo Saipov has been charged with federal terrorism offenses in connection with Tuesday's attack in Manhattan in which eight people were killed, according to a charging document from the US Attorney for the Southern District of New York. Saipov, a 29-year-old Uzbek national who was living in New Jersey, is charged with providing material support to ISIS and violence and destruction of motor vehicles.
Saipov rented a truck similar to the one used in the attack several times over the course of the last several weeks in order to be familiar with operating it, a law enforcement official tells CNN.

The suspect in New York's deadliest terror attack since 9/11 had planned the attack for weeks and carried out the killings "in the name of ISIS," John Miller, NYPD deputy commissioner for intelligence and counterterrorism, said on Wednesday.
Authorities identified the suspect as Sayfullo Habibullaevic Saipov, a 29-year-old Uzbekistan native who came to the US legally in 2010. Saipov allegedly drove a rented truck onto a well-trafficked bike path just blocks from the World Trade Center on Tuesday afternoon.
Eight people were killed and more than a dozen injured as the driver carved a path of destruction through several blocks of Lower Manhattan. Saipov crashed the rented truck into a school bus, left the vehicle brandishing imitation firearms and was shot by police, officials said. He survived and was taken into custody, police said.
In carrying out the attack, Saipov relied on the playbook laid out by ISIS in recent years, officials said. Miller said that handwritten notes in Arabic found near the scene had both symbols and words, but the general message was that the Islamic State would endure forever.
"He appears to have followed almost exactly to a 'T' the instructions that ISIS has put out in its social media channels before with instructions to their followers on how to carry out such an attack," Miller said.
Here are the latest developments:
- Five Argentinian high school classmates, two young American men, and a Belgian mother were identified as the victims, police said.
- President Donald Trump called Mayor Bill de Blasio and Gov. Andrew Cuomo to offer any federal assistance needed, Trump tweeted.
- The suspect arrived in the US as part of the diversity immigrant visa program, the Department of Homeland Security said.
- De Blasio and Cuomo praised New York residents for quickly returning to their normal lives. If the attacker's goal was to terrorize the public, then that goal failed, they said. "That's what makes New Yorkers special," de Blasio said. "That strength, that resilience, that ability to be undeterred in the face of ugliness and the actions of a depraved coward."
Saipov came to the US from the central Asian nation of Uzbekistan in 2010 on a diversity immigrant visa, according to the Department of Homeland Security. The Diversity Immigrant Visa Program awards up to 50,000 individuals per year a visa for a green card, which bestows permanent residency and is a path to citizenship.
The visas are awarded randomly to those in select countries to promote immigration from places that don't otherwise send many immigrants to the US. The bill establishing the program was signed into law in 1990.
NYPD official John Miller said Saipov has never been the subject of an NYPD or FBI investigation, but investigators are looking into how he is connected to the subjects of other investigations.
Saipov was "radicalized domestically" in the US, Gov. Andrew Cuomo said Wednesday morning.
"The evidence shows -- and again, it's only several hours, and the investigation is ongoing -- but that after he came to the United States is when he started to become informed about ISIS and radical Islamic tactics," Cuomo said.
Saipov was not on any US government terror watch lists, according to two sources familiar with the investigation.
Just over six months ago, Saipov began driving for Uber in New Jersey, the company told CNN. He passed a background check and did not have any rider complaints about his safety as a driver, according to Uber. The company is cooperating with authorities in the investigation.
Saipov once listed his occupation as a truck driver, his marriage license shows.
He had multiple run-ins with law enforcement in several states, online records show. He had traffic citations issued in Missouri and Pennsylvania and was arrested by the Missouri State Highway Patrol in October 2016 after failing to show up in court for a misdemeanor offense.
He paid a $200 bond, which he forfeited when he didn't show up in court for his next hearing in November. A guilty plea was entered on his behalf.
Saipov's wife has spoken with investigators, law enforcement officials said. Saipov, his wife and three children have a residence in Paterson, New Jersey.
Carlos Batista, one of Saipov's neighbors in Paterson, told CNN that Saipov had acted as a "peacemaker" about six months ago. Batista was riding a dirt bike at night, and Saipov's friends asked him to stop. The incident became testy until Saipov stepped in and "calmed everything down," Batista said.
Saipov has been linked to social media accounts that contain ISIS-related material, a law enforcement official said Wednesday morning. The official also said Saipov has been somewhat cooperative with FBI and New York police investigators who questioned him in the hospital overnight.
Officers were able to talk to Saipov before he went into surgery, but it was unclear if he told them anything, a law enforcement source told CNN.
Among the eight people killed, five were from Argentina, two were Americans, and one was from Belgium, according to the New York Police Department.
The Argentinians were part of a group celebrating their high school reunion in New York City, Argentina's Foreign Affairs Ministry said.
Hernán Diego Mendoza, Diego Enrique Angelini, Alejandro Damián Pagnucco, Ariel Erlij and Hernán Ferruchi died in the attack, the ministry said in a statement Tuesday.
They had traveled to New York from Rosario, a town nearly 200 miles northwest of Buenos Aires, to mark the 30th anniversary of their high school graduation. A sixth Argentine national who was also part of the group was injured during the attack.
Nicholas Cleves, 23, from New York, and Darren Drake, 32, from New Milford, New Jersey, were the two Americans killed.
Anne-Laure Decadt, a 31-year-old Belgian woman, was also among those killed, according to a statement from her husband, Alexander Naessens. Decadt, a mother of two young sons, was on a trip to New York with her two sisters and her mother, Naessens said.
The President's response
Hours after the attack, President Donald Trump tweeted that he's ordered the Department of Homeland Security "to step up our already Extreme Vetting Program", and he accused Sen. Chuck Schumer of not being tough enough on immigration.
Speaking to the media on Wednesday, Trump called the suspect an "animal" and said that he planned to start the process of terminating the diversity lottery program.
"I am going to ask Congress to immediately initiate work to get rid of this program. Diversity lottery, diversity lottery. Sounds nice, it is not nice, it is not good. It hasn't been good and we have been against it," he said.
Earlier Wednesday, Gov. Cuomo criticized Trump's tweets.
"The President's tweets were not helpful. I don't think they were factual. I think they tend to point fingers and politicize the situation," he said.
"You play into the hands of the terrorist to the extent that you disrupt, divide and frighten people in the society. The tone now should be the opposite -- on all levels."
New York City Mayor Bill de Blasio said "the last thing we should do is start casting aspersions on whole races of people or whole religions or whole nations. That only makes the situation worse."
De Blasio also warned against stereotyping all Muslims as extremists.
"Anyone who wants to come into this country should be very thoroughly vetted as an individual," he said. "But the minute you start generalizing it, especially to a whole religion, then unfortunately we're sending the exact negative message that a lot of our enemies want and the terrorist wants to affirm -- that this nation is somehow anti-Muslim. We've got to do the exact opposite."
Vehicles as weapons
The tactic of turning an ordinary vehicle into a lethal weapon is becoming increasingly common.
In 2014, an ISIS spokesman called for lone-wolf attacks using improvised weaponry. "If you are not able to find an IED or a bullet, then single out the disbelieving American, Frenchman or any of their allies. Smash his head with a rock or slaughter him with a knife or run him over with your car or throw him down from a high place or choke him or poison him."
Since 2014, there have been 15 vehicular attacks in the West by jihadist terrorists, killing 142 people, according to a count by New America, a nonpartisan research institution. Those figures include Tuesday's attack in Manhattan.
For the past few years, New York police have reached out to vehicle rental businesses to warn them about possible terror threats.
"We did extensive outreach to the truck rental business. We visited over 148 truck rental locations in this area," Miller said Tuesday. "The industry has had a high level of awareness on this matter from the NYPD."
Miller said that if a company is suspicious of a would-be renter, they usually delay or simply deny a rental to let police investigate.
In Tuesday's incident, the suspect drove a Home Depot rental truck he drove from New Jersey, Miller said.
