A plane carrying 81 people, including a top Brazilian football team, has crashed on its approach to the city of Medellin in Colombia, officials say.
Reports say there are 76 dead and 5 survivors.
The chartered aircraft, flying from Bolivia, was carrying members of the Chapecoense football team, airport officials said.
The team was 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.
The South American Football Confederation (Conmebol) said it was suspending “all activities”.

Chapecoense issued a brief statement saying: “May God be with our athletes, officials, journalists and other guests travelling with our delegation.”
It said it would refrain from any further statements until it had assessed the extent of the crash.
Reports suggest that at least two members of the team – Alan Ruschel and Danilo – may have survived.
The sports network Telemundo Deportes tweeted (in Spanish) that Ruschel was in shock but conscious and talking, and asked to keep his wedding ring and to see his family.
The mayor of the nearby town of La Ceja confirmed that a 25-year-old footballer was among the survivors.
He said that 25 people were known to have died.
The team, from the southern city of Chapeco, was promoted to Brazil’s first division in 2014 and reached the final last week after a victory against Argentina’s San Lorenzo.
Reports say the British Aerospace 146 short-haul plane, operated by Bolivian charter airline Lamia and carrying 72 passengers and nine crew, crashed in Cerro Gordo in the municipality of La Union shortly before midnight local time (05:00 GMT).
According to an airport press release, it was reporting an electrical fault to the control tower.
Medellin’s Mayor Federico Gutierrez described it as “a tragedy of huge proportions”.
The Jose Maria Cordova de Rionegro airport, which serves Medellin, posted on its Twitter account: “Confirmed, the aircraft licence number CP2933 was carrying the team @ChapecoenseReal. Apparently there are survivors.”
It later said in a statement that “all possible aid was being mobilised because five survivors are being reported”.
Poor weather has meant that the crash site, in a mountainous area, is only accessible by land.
However, there was no fire on impact, which has given rescuers hope that more survivors may be found.
Conmebol said in a statement that its president, Alejandro Dominguez, was on his way to Medellin.
“The Conmebol family greatly regrets what happened. All activities of the confederation are suspended until further notice,” it said
