New Delhi : Pollution levels in Delhi have spiked again, pushing the air quality of the national capital and surrounding areas from 'moderate' to 'severe category.
Strong-anti cyclonic winds blowing from Rajasthan are the reason behind the worsening air quality.
On Wednesday morning, many places in Delhi saw the air quality index (AQI) touching above 500, causing hazy conditions and leading to a dip in visibility.
The AQI of R.K. Puram read 660, while other places like Okhla Phase-II (738), PGDAV College, Sriniwaspuri (686), Punjabi Bagh (714), Mandir Marg (545) and ITO (816) saw the air quality plummet to hazardous levels.

However, Faridabad recorded an AQI of 175 in the 'moderate category', the lowest among all in the Delhi-NCR region, as per AQICN.
It is to be noted that a number of dust storms have struck the northern part of India several times in this year's summer season, causing casualties and loss of properties.
