NEW YORK (AP) — A Mexican navy sailing ship hit the Brooklyn Bridge on Saturday during a promotional tour in New York City, the top of its three masts slamming into the iconic span and partially collapsing as the boat floated in the East River.

The New York Fire Department press desk confirmed that authorities responded to injuries but had no details about how many people might have been hurt or whether they were on the vessel or on the bridge.

In a scene captured in multiple eyewitness videos, the masts could be seen snapping and partially collapsing as they crashed into the deck of the bridge. Videos showed heavy traffic on the span at the time of the collision.

The vessel, which was flying a giant green, white and red Mexican flag, then drifted toward the edge of the river as onlookers scrambled away from shore.

Sydney Neidell and Lily Katz told The Associated Press they were sitting outside to watch the sunset when they saw the vessel strike the bridge and one of its masts snap. Looking closer, they saw someone dangling from high on the ship.
