• Two other victims remain unidentified.

At least eight people have died, and 11 were injured in a terror attack in lower Manhattan, New York City, on Tuesday.

Sayfullo Habibullaevic Saipov, a 29-year-old Uzbeki national, is suspected to have rammed a pickup truck into cyclists and pedestrians in a bike lane, collided with a school bus, and threatened people with fake guns, police said.

The victims included five Argentinians and one Belgian. Two other victims remain unidentified. Six of the victims died at the scene, while two died of their injuries in hospital, The New York Times reported.

The five Argentinians were friends from Rosario, a port city in northern Argentina, the country's foreign ministry said. They were in New York City to celebrate the 30th anniversary of their high school graduation from Rosario's Polytechnic School.

Ariel Erlij

Ariel Erlij, 48, was one of the five Argentinians killed.

He was the owner of Ivanar, a steel company in Rosario, according to Argentine newspaper La Nación. He was married, had at least two children, and was a fan of the Rosario Central football club, Argentinian news agency Télam reported.

He encouraged the reunion trip and helped pay for some of his friends' tickets to New York, The Guardian said. The group had rented bicycles and walked around lower Manhattan when they were hit, La Nación said.

Four other members of the group of ten managed to escape the scene unharmed and have already communicated with their families, Argentinian newspaper Clarín reported.

A sixth friend, Martín Ludovico Marro, was recovering from his injuries at Manhattan's Presbyterian Hospital, the Argentinian Foreign Ministry said.

The municipality of Rosario - where the friends grew up - has declared three days of mourning.

Woman from Belgium, 31

A 31-year-old Belgian woman was caught up in the attack, Didier Reynders, Belgium's deputy prime minister and foreign affairs minister, told Belgian newspaper Het Laatste Nieuws.

The woman, who was from Staden, a village in western Flanders. She was in the city with her mother and two sisters, Reynders said. Staden has lowered its flags to half-mast, HLN added.

"It's so unreal that this can happen," Staden Mayor Francesco Vanderjeugd said. "A few days ago, I sent a text to one of the sisters when I saw on social media that she was in the United States. I wished them a beautiful trip, hoping they would enjoy each other's company and Halloween."

Reynders also said three Belgians were injured and "in the operation room."
