Malaysia's landmark Putra Perdana, the office of the Prime Minister, is shrouded with smog in Putrajaya, outside Kuala Lumpur on July 23.

The haze is back in some parts of Malaysia's peninsular and is expected to spread further inland over the next few days, said the Meteorological Department, as reported by The Star. The Air Pollutant Index for the Cheras areas in Kuala Lumpur at 2:00 p.m. (0600 GMT) on Tuesday was at 98, according to the Ministry of Natural Resources and Environment. A reading between 50 to 100 indicates that air pollution is moderate while 100 and 200 is unhealthy. Reuters/Bazuki Muhammad
