The powerful propellers on a U.S. Marine Corps aircraft have blown tree branches into people on the ground during a Memorial Day demonstration in a New York City park.
Firefighters say 10 people suffered minor injuries.

The Osprey MV-22 aircraft was landing at Staten Island's Clove Lakes Park around 9 a.m. Monday as part of Fleet Week. The MV-22 combines airplane-like wings with rotors that let it take off and land vertically, like a helicopter.

Marine Corps spokesman Lt. Josh Diddams says the wind generated by the aircraft's propellers broke branches off a nearby tree. The branches were swept into some people on the ground.

Firefighters say seven people have been taken to Richmond University Medical Center. Three others refused medical attention.
