Forest fires are reported to be spreading out of control once more, in Kalimantan in the Indonesian part of the island of Borneo.
The resurgence of the bush and forest fires has raised fears that South-east Asia could soon be blanketed by another smoke haze.
International experts say the Indonesian government does not have the people and equipment to put the fires out, and only rain expected in May will be sufficient to do the job.
If the fires continue in Kalimantan and hotspots flare up in Sumatra, then Brunei, Malaysia, Singapore, southern Thailand and the Philippines could see a repeat of the severe air pollution which blotted out the sun at the end of last year.
