Acidente em Nova Iorque?

Two people have been killed when a small aircraft crashed into a building in New York City's affluent Upper East Side, police say.

Flames and smoke are coming out of the 50-storey apartment building on Manhattan island.

The FBI says there is no indication that the crash is terrorism-related. A White House spokesman said they were not ruling out any theory.

As a precaution, fighter planes are now flying over a number of US cities.
