The haze, which has shrouded parts of Malaysia and Singapore for about a month, also spread to Thailand today, the first time it has reached hazardous levels so far north.
It highlights the regional nature of a problem that's being blamed on Indonesia's inability to prevent big plantation companies from burning forests to clear land for new trees.
The air pollutant index hit the hazardous level in Shah Alam, the capital of Malaysia's central Selangor state, and was very unhealthy in many other areas. That prompted authorities to order the closure of 7,000 schools today and tomorrow, even though the situation eased early today.
The poor visibility forced several airports in Malaysia to be closed for hours yesterday. A popular annual marathon in Kuala Lumpur was also canceled.

Deputy Prime Minister Zahid Hamidi said Indonesia's efforts to crack down on the sources of open burning by farmers were not enough. He said Indonesia should seek more help from its Southeast Asian neighbors to tackle the haze, which is an annual problem.
Malaysia's national news agency, Bernama, quoted Zahid as saying that Malaysia welcomes the measures announced by Widodo, but that "three years is too long."
"We hope its commitment is not only on paper or mere statements pleasant to the ears, but through implementation which could end all haze problems," Zahid said.
Today, haze was also reported in the southern Thai provinces of Songkhla, Trang, Yala and Pattani, which are closest to Malaysia.
Wijarn Simachaya, director general of Thailand's Pollution Control Department, told The Associated Press that "the situation is getting worse."
He said it was the first time this year that the pollution from haze had reached the 171 mark in Songkhla. "This is the level that could have bad effect on health," he said. The previous worst level was 136.
