The Bolivian Civil Aviation Authority has indefinitely removed the license of tiny charter airline LaMia following the crash of one its charter planes in Colombia on 28 November.
The LaMia flight crashed into a mountainside while approaching Medellin, Colombia, killing all but six of the 77 people on board, including many players from Chapecoense football club.
