A Delhi court on Monday remanded three protesters to three days of police custody in a case relating to the alleged use of pepper spray on police personnel during a demonstration at the India Gate over pollution last month.

Mumbai's air quality has shown a marked improvement since November 26, owing to multiple pollution-control measures in the city and its suburbs, while show-cause notices have been issued to 482 construction sites for violating pollution norms.

The Commission for Air Quality Management (CAQM) said on Monday that incidents of farm fires in Punjab and Haryana reached their lowest levels during the 2025 paddy harvesting season.

A day after a slight improvement, the air quality in the capital slipped back to the 'very poor' category at 304 on Monday, marking a return to the prolonged pollution spell Delhi has been battling this winter.

For most of October and November, Delhi pollution levels hovered between 'very poor' and 'severe', fuelled by a rising "toxic cocktail" of PM2.5, nitrogen dioxide (NO2) and carbon monoxide (CO) emitted mainly from vehicles and other local sources.

A monitoring mechanism has been put in place to oversee the implementation of 95 directions of the Centre-appointed Commission for Air Quality Management, Union minister Bhupender Yadav told the Lok Sabha today.

Union Minister Bhupendra Yadav said that while farm fires remain an episodic contributor to winter pollution, Delhi's air quality is influenced by multiple factors, including vehicular emissions, industrial pollution and construction dust.

The Supreme Court on Monday told the Commission for Air Quality Management (CAQM) and state authorities in the National Capital Region (NCR) to come up with a clear, time-bound, and "actionable" strategy to address Delhi's recurring air pollution.

Mumbai's civic body, the Brihanmumbai Municipal Corporation (BMC), has halted construction and dust-generating activities.
