Malaysia has declared a state of emergency in two southern districts after smog triggered by forest fires in Indonesia reached hazardous levels.

Close to a hundred forest fires are still burning on the Indonesian Island of Sumatra, according to the authorities there.

Illegal land clearing fires on the island are being blamed for causing the thick smog that has enveloped the entire region - raising the pollution levels in cities like Singapore and Kuala Lumpur.
