Five friends from Argentina were among those killed in a truck attack in New York on Tuesday.
Eight people were killed and 11 injured when the driver of the truck hit people on a cycle path in Lower Manhattan.
A 29-year-old man, reported to be an Uzbek immigrant, was shot and injured by police as he left the vehicle.
US President Donald Trump has ordered the Department of Homeland Security to "step up" vetting measures in the wake of the attack.
The suspect reportedly shouted "Allahu Akbar" ("God is greatest") as he left the truck. Officials said it was a terror attack.
The deaths of the five Argentines were confirmed by the country's foreign ministry. They were part of a group of 10 friends in New York to celebrate the 30th anniversary of their graduation from a polytechnic college in the central city of Rosário, Argentine media said.
One of the men who died, steel firm owner Ariel Erlij, helped pay for the friends' trip, La Nación newspaper reported (in Spanish).
Argentina's foreign ministry named the men - all reportedly aged 48 or 49 - as Diego Enrique Angelini, Alejandro Damian Pagnucco, Ariel Erlij and Hernan Ferruch. Another of the friends, Martin Ludovico Marro, is being treated in hospital.
Three days of mourning have been called in Rosário, Clarín newspaper reported.
A Belgian national was also killed, Belgium's foreign minister said. Two other victims have not yet been identified.
How did the attack unfold?
At a news briefing, New York Police Department (NYPD) Commissioner James O'Neill said:
- Shortly after 15:00 local time (19:00 GMT), a white pick-up truck rented from retailer Home Depot struck cyclists and pedestrians while being driven along the West St-Houston St path for many blocks
- The vehicle then hit a school bus, injuring two adults and two children on board, and came to a halt
- The driver emerged holding what appeared to be two handguns and made a statement "consistent with a terror attack"
- He was shot in the abdomen by a police officer stationed near the scene
- A paintball gun and a pellet gun were recovered from the scene
Mangled bicycles littered the scene of the attack, which occurred as much of the city was celebrating Halloween.
