A plane carrying 72 people, including football players from Brazil, has crashed in Colombia. The flight had left Bolivia and was on its way to Medellin’s International airport.

It’s not clear if there are any survivors. Local media reports said among the passengers were members of a soccer team which is scheduled to play Copa Sudamerica finals on Wednesday in Medellin.

Medellin’s Mayor Federico Gutierrez said that it is possible there are survivors.

“It’s a tragedy of huge proportions,” Gutierrez told Blu Radio on his way to the site in a mountainous area outside the city where the chartered aircraft is believed to have crashed shortly before midnight local time.

He said ambulances and rescuers were on their way. The crash was caused by lack of fuel.

Medellin airport later confirmed that the aircraft, which departed from Bolivia, was transporting the Chapecoense soccer team from southern Brazil.
