According to many witnesses, Saipov shouted “Allahu Akbar” upon exiting a Home Depot rental truck after intentionally driving the wrong way on a busy bike lane near the World Trade Center — the site of the deadliest terror attack on U.S. soil. After striking several people, witnesses say he “crashed deliberately into a school bus carrying at least three children,” CNBC reports. Leaving his vehicle with two imitation guns, he was shot in the abdomen by police, according to NYPD.

Saipov was reportedly taken to Bellevue Hospital and is in police custody. A paintball gun and pellet gun were recovered at the scene, according to law enforcement officials.

Six of the victims — all men — were pronounced dead at the scene, while two died later, Police Commissioner James O’Neill said.

At a press conference, De Blasio confirms that, based on the information available, this was an act of terror. He also gave an updated casualty count: 8 deaths.

I'm with Commissioner O'Neill and Governor Cuomo in Lower Manhattan with an update on this afternoon's incident. https://t.co/7000xigDge — Mayor Bill de Blasio (@NYCMayor) October 31, 2017

“This was an act of terror, and a particularly cowardly act of terror aimed and innocent civilians, aimed at people going about their lives who had no idea what was about to hit them,” said De Blasio. “We, at this moment … know of 8 innocent people who have lost their lives and over a dozen more injured. We know that this action was intended to break our spirit, but we also know New Yorkers are strong, New Yorkers are resilient, and will not be moved by an act of violence.”

“I want to ask all New Yorkers to be vigilant. We know its Halloween night and in the days ahead people will be uneasy,” he continued.

After De Blasio spoke, Governor Cuomo spoke, reiterating there is no ongoing threat:

“It reminds us how precious life is… that shock and that pain is going to be very real… our first responders did an extraordinary job… the new terrorist tactic which they called for publically are these lone wolves who commit an act of terror. This is very preliminary … but at this moment there is no evidence to suggest a wider plot or wider scheme… the actions of one individual who meant to cause pain and harm and probably death, and the resulting terror, and that was the purpose. We will be vigilant, more police everywhere, you’ll see them in the airports, you’ll see them in the tunnels, it’s not because there is any evidence of any threat.”
