The Turkish Airlines Boeing 737-800, which had 127 passengers and seven crew members according to the airline, broke into three pieces on impact in a field near Schiphol Airport.
The injured included both crew and passengers, said Assistant Local Mayor Michel Bezuijen.
It is too early to determine the cause of the crash, Bezuijen said.
A news photographer at the scene said she saw an unknown number of bodies lying under a white blanket, Maaike Voersma, a journalist with Dutch newspaper De Bers, told CNN.
A passenger on the plane who spoke to Turkish network DHA said he saw injured people trapped and squeezed between the seats when he walked off the plane.
