A plane carrying 81 people, including a top Brazilian football team, has crashed on its approach to the city of Medellin in Colombia.

Colombia's civil aviation body says only six people survived the crash, that occurred on a mountainside.

The chartered aircraft, flying from Brazil via Bolivia, was carrying members of the Chapecoense team.

The team had been due to play in the final of the Copa Sudamericana, against Medellin team Atletico Nacional.

The first leg of the final of the cup, South America's second most important club competition, was scheduled for Wednesday but has now been suspended.

Organisers say Atletico Nacional has asked for Chapecoense to be awarded the cup.

The match was seen as the biggest in the history of the relatively small club, which entered Brazil's top division for the first time in 2014.

Brazilian President Michel Temer announced three days of national mourning, and top Spanish clubs Real Madrid and Barcelona held a minute's silence at the beginning of their practice sessions.
