Aerial footage taken from an aeroplane above Bangkok shows farmers still burning their crops - even as authorities battle to contain deadly levels of smog.

A thick cloud of pollution has engulfed the city for the last two weeks leading to mass sicknesses and warnings from health experts about the deadly cocktail of pollutants.

Authorities have been spraying water into the air to try and increase moisture and disperse the smog.

But footage of sugarcane husks being burned on the outskirts of Bangkok shows how the efforts are in vain, as farmers continue adding to the pollution.

The video was shot from the passenger seat of an Airbus A320 as it came in to land at Bangkok's Don Mueang Airport.
