Five million masks are being distributed at schools in India’s capital, Delhi, after pollution made the air so toxic officials were forced to declare a public health emergency.

A Supreme Court-mandated panel imposed several restrictions in the city and two neighbouring states, as air quality deteriorated to severe levels.

Dangerous particulate levels in the air are about 20 times the WHO maximum.

All construction has been halted for a week and fireworks have been banned. The city will introduce a temporary scheme so that only cars with odd or even-numbered licence plates can drive on given days, in a bid to cut traffic pollution.

Delhi's Chief Minister Arvind Kejriwal says the city had been turned into a gas chamber.
