Beijing tests emergency smog alert system

Colour-coded warning system is the latest measure to tackle the city's growing problem of pollution.

    The Chinese capital's pollution levels are considered so hazardous that children and the elderly are being told to remain indoors, or wear masks if they venture outside.

    Now the government has introduced a new colour-coded alert system that tells people how serious the problem is.

    Al Jazeera's Rob McBride reports from Beijing.
