SINGAPORE - A fire in a Malaysian landfill is the source of the haze that has affected dwellers in parts of Singapore over the past few days.

Minister for the Environment and Water Resources Vivian Balakrishnan confirmed this in a Facebook post on Sunday night.

He said that the fire started in the Pasir Gudang landfill last Thursday and smoke from it was blown to Singapore by north-east winds.

Pasir Gudang is an industrial town east of Johor Bahru.

"(The Malaysian authorities) are still trying to resolve the problem," he said in his post. "We stand ready to assist if requested."
