NEW DELHI (AP) — Schools were closed indefinitely and some coal-based power plants shut down as the smog-shrouded Indian capital and neighboring states invoked harsh measures Wednesday amid considerations of a lockdown in New Delhi to combat worsening air pollution.

India’s top court is deliberating on the lockdown — a first of its kind in the country to stem pollution and not to control coronavirus infections.

It’s not clear how far it would go, but the New Delhi government has already shown its willingness to impose an emergency weekend lockdown, similar to the one implemented during the pandemic. It’s now waiting for the Supreme Court’s decision, which could come as early as Nov. 24.
