Indonesian, Malaysian and Singaporean authorities have dismissed research that smoky haze from catastrophic forest fires in Indonesia last year caused 100,000 deaths.
Some even contend the haze caused no serious health problems, but experts said those assertions contradict well-established science.
Last year’s fires in Sumatra and the Indonesian part of Borneo were the worst since 1997, burning about 261,000 hectares of forests and peatland and sending haze across the region for weeks. Many were deliberately set by companies to clear land for palm oil and pulpwood plantations.

In Indonesia, a spokesman for the country’s disaster mitigation agency said the research “could be baseless or they have the wrong information”. Indonesia officially counted 24 deaths from the haze including people killed fighting the fires.
