(CNN) -- Eight people were killed and about a dozen were hurt Tuesday when a 29-year-old man drove a rental truck into crowd, mowing down pedestrians and cyclists in what officials are calling the deadliest terror attack in New York City since 9/11.

Here's what we know -- and don't know -- so far.

What happened?

What we know:

  • A man drove a rented truck around 3:05 p.m. onto the West Side Highway bike path in New York's lower Manhattan, hitting bicyclists and pedestrians.
  • About a mile down the path, the truck collided with a school bus, injuring two adults and two children. The driver, identified by two law enforcement sources as Sayfullo Habibullaevic Saipov, exited the truck with a pellet gun and a paintball gun.
  • A police officer shot him in the abdomen.
  • One official said Saipov followed ISIS instructions "for carrying out such an attack" almost to the letter. The terror group has posted instructions on its websites and on social media.

What we don't know:

What was the attacker's motive? Police say Saipov has been somewhat cooperative, but what is he telling them?

The victims

What we know:

  • Hernán Diego Mendoza, Diego Enrique Angelini, Alejandro Damián Pagnucco, Ariel Erlij and Hernán Ferruchi were killed while celebrating the 30th anniversary of their graduation from their high school in Rosario, Argentina.
  • A Belgian mother of two, Anne-Laure Decadt, was also killed, according to her husband. She was traveling with her sisters and mother at the time of the attack.
  • Also killed were Darren Drake, 32, of New Milford, New Jersey, and Nicholas Cleves, 23, of New York, said a source with knowledge of the investigation.
  • Another Argentine who was part of the group was injured in the attack, as was a German woman who was not with the group.
  • Two victims died at Bellevue Hospital.
  • Of the injured, nine remain hospitalized. Four of those are in critical but stable condition, officials said.
  • Injuries included a bilateral amputation and trauma to the neck, head, chest and back.

The police officer

What we know:

His name is Ryan Nash, 28. He was "on post near the location" at the time of the attack and apprehended Saipov, Police Commissioner James O'Neill said He's been with the New York Police Department since 2012 and works in the city's 1st precinct. O'Neill says he "stopped the carnage" by shooting Saipov in the abdomen. "He was so humble about his achievement, it was very striking," Mayor Bill de Blasio said.

What we don't know:

Whether Nash is one of the officers with whom Saipov spoke after he was shot, and if so, what did Saipov tell him?

The suspect

What we know:

  • Saipov has been linked to social media accounts containing ISIS-related material, and a note found near the truck used in the attack claimed the action was taken in the name of the terror group, authorities say. The crux of the note, one official said, is that ISIS will endure forever.
  • Saipov came to the United States in 2010 from Uzbekistan. He apparently spent time in Florida at some point.
