The Supreme Court resumed hearing on a case related to construction in the Delhi-NCR region which was banned by the top court in view of the deteriorating air quality.
On Thursday, Supreme Court expressed dissatisfaction with the measures taken over the last few weeks. Warning of strict action, the court gave a 24-hour ultimatum to centre, Delhi, and neighboring states to act against industrial and vehicular pollution - counted as the main causes behind the deteriorating air quality.
Delhi's air quality deteriorated sharply last month after Diwali. Farm fires were also cited as a source - but that led to debates and blame games. A month on, the city is still gasping for air.
