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).

The air quality in Delhi remained in the "very poor" category with the Air Quality Index plummeting further to 385, according to the Central Pollution Control Board. Additionally, some of the areas in the national capital logged air quality in the "severe" category.
