SINGAPORE (Reuters) - Singapore's air pollution hit levels classified "unhealthy" on Friday, the government's National Environment Agency said on its website. (http://www.haze.gov.sg)
The 3-hour Pollution Standards Index (PSI) in the city-state rose to 102 at 4 p.m. local time (0800 GMT). A PSI reading above 100 indicates air pollution has reached an "unhealthy" level.
The PSI level in the island-nation hit a record-high of 401 in June 2013, when smoke from forest burning in Indonesia engulfed the city.
