Melbourne records worst air quality of any city in the world
Hazardous smoke will blanket Melbourne for a second day on Wednesday after the city recorded the worst air quality of any city in the world earlier in the week.
The smoke has caused a number of flight delays into Melbourne and is triggering smoke alarms.
The fire brigade was called out to 200 false alarms between Monday night and Tuesday and ambulance crews responded to more than 160 cases of breathing problems.
Forecast rain for Wednesday night will bring reprieve, but air quality is expected to remain poor until later in the week.
Vulnerable groups including children, the elderly, and those with pre-existing medical conditions have been urged to stay indoors.
