Shiv Sena (UBT)'s Aaditya Thackeray said Mumbai is competing with Delhi in the "terrible AQI race". "Governments from top to bottom, currently controlled by BJP and its allies, conveniently ignore the plight of the people...All they care about is builders," he added. AQI levels in various parts of Mumbai exceeded 300, while in parts of Navi Mumbai it crossed 400.
