Authorities are responding to an emergency after an airplane with 72 people on board has crashed on its way to Medellin's international airport.

Medellin's international airport said on its Twitter account that the aircraft had departed from Bolivia.

It's not clear if there are any survivors. But local media reported that the charter aircraft was carrying members of the soccer team Chapecoense from Brazil, which is scheduled to play Copa Sudamerica finals against Atletico Nacional on Wednesday in Medellin.
