Air pollution in the north of India has "reached unbearable levels," the capital Delhi's Chief Minister Arvid Kejriwal says.

Axar.az reports citing BBC.

In many areas of Delhi air quality deteriorated into the "hazardous" category on Sunday with the potential to cause respiratory illnesses.

Authorities have urged people to stay inside to protect themselves.

Mr Kejriwal called on the central government to provide relief and tackle the toxic pollution.

Schools have been closed, more than 30 flights diverted and construction work halted as the city sits in a thick blanket of smog.

Delhi Health Minister Satyendar Jain advised the city's residents to "avoid outdoor physical activities, especially during morning and late evening hours".

The advisory also said people should wear anti-pollution masks, avoid polluted areas and keep doors and windows closed.
