UPDATE | Some injuries reported in airplane fire in Fla.

DANIA BEACH, Fla. (AP) — A jet plane's engine caught fire today as it prepared for takeoff, and passengers had to quickly evacuate using emergency slides, officials said.

Broward Sheriff Fire Rescue spokesman Mike Jachles said there were "some injuries" but offered no further details. Dozens of passengers could be seen in video footage gliding down the slides and running away from the plane to the terminal as fire crews rushed to put the blaze out.

It's not clear how many people were on board the Dynamic Airways flight headed to Caracas, Venezuela, from the Fort Lauderdale/Hollywood International Airport. The Boeing 767 was set to take off at 12:45 p.m. when it caught fire, Federal Aviation Administration spokeswoman Kathleen Bergen said.

Passengers on another plane on the runway recorded the fire and posted video to Twitter showing plumes of thick black smoke coming from the plane.

A pilot in an aircraft taxiing behind the Dynamic Airways plane reported fuel leaking from it before the fire, Bergen said.

An audio recording posted by WSVN showed that an air traffic controller told the pilot "a lot of fluid" was leaking from his left engine. The controller then urgently tells the pilot that the engine had caught fire and that he was dispatching firefighters.
