Plane skids from runway at Chicago airport after massive winter storm

A United Airlines plane has skidded off a runway at Chicago's O'Hare International Airport amid snowy and icy weather.

Chicago fire officials say the incident occurred Sunday morning (local time). No injuries were reported. The flight came into the airport from Phoenix and 129 people were on the plane.

A massive winter storm has brought up to 25 centimetres of snow to some parts of the Midwest and is expected to hit the Northeast overnight.

The storm prompted the cancellation of nearly 1,000 flights at Chicago's airports. The average delay at O'Hare International Airport was nearly an hour.
