Jakarta’s air quality a major concern ahead of Asian Games

The Asian Games are the world’s second-largest sports event after the Olympics, with 14,000 athletes taking part from 45 Asian countries.

Those athletes will take part in 462 medal events across 47 sports.

Jakarta has undergone a big tidy up ahead of the event, but air pollution is still a big problem.
