Family and friends have gathered outside the club in west Rio as they await answers as to what happened.

The club said shared a message on Twitter stating that it is in mourning following the tragedy.
A match due to take place on Saturday against a rival club has been cancelled.
Speaking to reporters at the scene, Jefferson Rodrigues, who runs a small bar near the club, said he had reached a 15-year-old player he is friends with. He said he was alive after spotting the flames and running.
“He lost his phone, and all of his things, but the important thing is he is alive,” he added.
