Asia smog: BBC visits smouldering forest in Indonesia

Thick haze from land-clearance fires in Indonesia has continued to shroud parts of Malaysia.

On Sunday Malaysia declared a state of emergency in two southern districts as air pollution levels reached a 16-year high, leaving two towns in virtual shutdown.

The smog is being blamed on illegal land-clearing fires burning in Indonesia's Sumatra island, mainly in Riau province.

The BBC's Rupert Wingfield-Hayes reports from the smouldering remains of a swamp forest in Dumai, in the province of Riau.
