The toxic smog continued to envelope the national capital on Tuesday morning, with reduced visibility in some areas that led to cancellation of many trains. The Air Quality Index (AQI) improved to an average reading of 308, even as the city government extended the ban on the entry of trucks till further orders.

Officials said light rain is expected on Wednesday, which might intensify the fog but could clear the smog.

8.00pm: “Delhi is out of emergency but not out of danger. In the coming days by November 16 and 17, the conditions are expected to get better. Unfortunately we are happy even though the air quality is very poor.
