Panic has gripped the Indian capital, Delhi, as residents woke up to a blanket of thick grey smog on 7th November.
Visibility has been poor as pollution levels have reached 30 times the World Health Organization’s recommended limit in some areas.
The Indian Medical Association (IMA) has declared “a state of medical emergency” and has urged the government to “make every possible effort to curb this menace”.
People have been posting dramatic pictures on social media showing the extent of the problem.
The Great Smog of Delhi is marked as one of the worst visualization of how bad air quality has become in New Delhi and adjoining areas in the National Capital Territory of India.
