DENVER – More than 100 passengers were evacuated from a Southwest Airlines plane on Friday at Denver International Airport after a cell phone battery started a fire in the cabin.

A Southwest spokesman said the plane was still at the gate when the fire started before 7 a.m. as it prepared to take off for Houston.

Passengers in the back of the plane used the rear emergency chutes while the crew extinguished the seat fire caused by the burning mobile phone.
