Forest fires spark smog crisis

PLEASE NOTE: EDIT CONTAINS CONVERTED 4:3 MATERIAL
Parts of Indonesia are shrouded in smog.
Visibility in Palembang in South Sumatra province was down to 200 metres because of it.
This is the cause.
Farmers and plantation owners elsewhere on Sumatra have been illegally clearing forestry for years.
Indonesia, the world's top palm oil producer, has repeatedly promised to tackle the problem but hasn't stamped it out.
Singapore, which also suffers bouts of the smog, has offered to send aircraft to help put out the fires.
Last year the smog was so bad Malaysia put out a poor visibility alert to shipping in the Malacca Strait.
