NEW DELHI, Nov 5 (Reuters) - India's capital territory of Delhi is keen to use artificial rain to fight air pollution this year, its Environment Minister Gopal Rai said on Tuesday, as deteriorating air quality in the region led to an increase in respiratory illnesses.

Delhi’s air quality continued to deteriorate on Tuesday, November 5, as pollution levels remained in the 'very poor' to 'severe' categories, according to data from the Central Pollution Control Board (CPCB).

Delhiites continued to breathe toxic air on Tuesday as the air quality edged closer to the severe zone in some areas.
