(CBS/AP) A small aircraft has hit an apartment building in New York, police said.

The building is described as a high-rise on Manhattan's upper east side, on 72nd street and York avenue. There's no word yet on any deaths or injuries.

There are conflicting reports on whether the aircraft was a small plane or a helicopter.

The Federal Aviation Administration only confirms that a "small plane" has crashed into a 22-story apartment building on East 72nd Street. They have not confirmed reports that it was a helicopter, reports CBS News correspondent Bob Orr.

Video from the scene shows the building fully engulfed in flames. A column of gray smoke rose over the city, and raging flames could be seen in four windows on two upper floors.

Meanwhile, New York Fire Department spokeswoman Emily Rahimi said an aircraft struck the 20th floor of a building on East 72nd Street. Witnesses said the crash caused a loud noise, and burning and falling debris was seen. Flames were seen shooting out of the windows.

It was not immediately known if the incident was an act of terrorism.
