NEW YORK (AP) — New York City Mayor Eric Adams says a family of Spanish tourists, including three children, died Thursday in a helicopter crash in the Hudson River that killed six people.

Adams said all of the dead have been recovered and removed from the water.

The helicopter broke apart in midair and crashed upside-down into the river between Manhattan and the New Jersey waterfront. It was the latest high-profile aviation disaster in the U.S., following other recent accidents in Washington and Philadelphia.

The New York Fire Department said it received a report of the crash at 3:17 p.m. All six people aboard were killed, a law enforcement official told The Associated Press. The official was not authorized to speak publicly and did so on condition of anonymity.

Witness Bruce Wall said he saw the helicopter “falling apart” in midair, with the tail and propeller coming off. The propeller was still spinning without the aircraft as it fell, he said.

Lesly Camacho, a hostess at a restaurant along the river in Hoboken, New Jersey, said she saw the helicopter spinning uncontrollably before it slammed into the water.

“There was a bunch of smoke coming out. It was spinning pretty fast, and it landed in the water really hard,” she said in a phone interview.

Video posted to social media showed parts of the chopper splashing into the water, and the overturned aircraft was submerged, with rescue boats circling it.

The skies were overcast at the time, but visibility over the river was not substantially impaired. Rescue crews had to deal with 45-degree water temperatures.

The National Transportation Safety Board said it would investigate.
