Shortly after takeoff, the plane lost speed and crashed and caught fire.
At least two explosions occurred, writes AP.
In addition to the players, who had their last day of isolation, the club's chairman was on board the six-seater Baron-model plane, where all six, including the pilot, died.
Quiet minute before all matches in Brazil
The Brazilian Football Federation has offered its condolences, as have Fifa and the South American federation Conmebol, and all matches regardless of league were preceded by a minute of silence on Sunday.
In 2016, 19 players from the club Chapecoense died when the plane ran out of fuel when the team was on its way to the final of the Copa Sudamericana, South America's equivalent of the Champions League, when the plane crashed outside Medellin.
In total, however, 71 people in that crash.
- Sadly, we know how this type of pain feels and we wished no other team would feel it.
But you do not bear this pain on your own, says Chapecoense in a statement.
The plane with the players belonging to the Division 4 team was on its way from the northern state of Tocantins to Goiania for a match against Vila Nova.
The cause of the crash is not known.
