Students, one wearing a face mask and the other covering her mouth with her headscarf, leave for home after an early dismissal from school due to the haze in Muar, in Malaysia's southern state of Johor bordering Singapore, June 20, 2013. Singapore's air quality deteriorated to "hazardous" levels on Thursday as smoke from forest fires in Indonesia obscured skies over the wealthy city-state and parts of Malaysia and disrupted some businesses and travel. At 11 a.m. (0300 GMT) on Thursday, Muar's pollution standards index (PSI) soared to 383, indicating a deterioration of air quality to "hazardous" levels, and forcing the temporary closure of 211 schools in the district, according to media reports.
