A plane carrying players from a Brazilian football team headed to Colombia for a regional tournament final, has crashed on its way to Medellin's airport, killing at least 71 people.
Police officials said that seven passengers had initially survived but one later died in hospital.
The entire Chapocoense football team - and an accompanying entourage of staff - were among 77 passengers and crew onboard the aircraft. Local reports said a large number of journalists were also on the plane.
Al Jazeera's Alessandro Rampietti, reporting from Bogota, said the flight crashed in a mountainous region.
"There have been heavy rains day in and day out in the last week or so," he said. "That could have played a big role in the crash, but that is still unconfirmed."
Medellin's Mayor Federico Gutierrez said that he was on his way to the region where the chartered aircraft was believed to have crashed shortly before midnight local time.
"It's a tragedy of huge proportions," he told Blu Radio.
It was not clear what caused the British Aerospace 146 short-haul plane to crash, but, as reported by Rampietti, Colombia had been hit by heavy rains and thunderstorms in recent hours.
