Haze shrouded Indias capital city again on Tuesday, with residents braving dangerous air quality to return to work after a weekend of clearer air and better weather.

A dip in wind speed and temperature is making air denser, trapping pollutants and worsening air quality, said Vivek Chattopadhyay, a senior programme manager at New Delhi-based non-profit Centre for Science and Environment.

Delhi is restricting the use of private cars until November 15 with an odd-even system - allowing cars on alternate days, depending on whether their licence plate ends in an odd or even number.
