The World Health Organization says the Ahvaz, Iran is the world's most polluted city.

In a new study, WHO says Ahvaz has the highest measured level of airborne particles small enough to cause serious health problems in humans. Ahvaz is a heavily-industrialized city known for oil fields.

WHO says cities in India, Pakistan, and Bostwana are also high on the list – and Mongolia is the world's most polluted country overall.

The city with the world's cleanest air, according to the WHO, is Whitehorse, the capital of Canada's Yukon province.

WHO says air pollution is responsible for about 1.3 million premature deaths worldwide every year.
