Singapore's haze deteriorated to ''hazardous'' levels late on Wednesday as smoke from slash-and-burn land clearing in Indonesia enveloped the city-state, inflaming tensions between the Southeast Asian neighbours. The Pollution Standards Index (PSI) soared to a record high of 321 at 10 p.m., up from 290 just an hour earlier and below 200 earlier in the day. A PSI reading above 300 indicates ''hazardous'' air quality, while a reading between 201 and 300 means ''very unhealthy''. REUTERS/Edgar Su
