New Delhi chokes under blanket of smog

Pollution levels in New Delhi have reached a three-year high. On Monday, the state air quality index for the city of 20 million people was at 436 — about nine times the recommended maximum.

Dense smog hung over central Delhi, where many pedestrians and bikers were seen wearing face masks. Authorities have declared a public health emergency, warning of a spike in locals suffering breathing difficulties, burning eyes and scratchy throats.

Delhi's India Gate, one of the capital's national monuments, was shrouded in a toxic cloud. The pollution prompted India's Supreme Court to order construction work across the city be halted until Tuesday. Authorities have also temporarily closed schools and handed out millions of pollution masks.

Delhi's chief minister, Arvind Kejriwal, who has compared his city to a "gas chamber," said in a video posted to Twitter that "there is smoke everywhere and people, including youngsters, kids, elderly are finding it difficult to breathe."

In an effort to tackle the smog, Delhi authorities banned half the capital's private cars from the roads. Under the regulation, vehicles must stay at home on alternate days, depending on whether their number plates end in an odd or even number. Motorbikes, scooters and public transport are are exempt from the "odd-even" scheme.

These traffic volunteers hold a sign urging motorists to "obey odd and even" and "remove pollution." More than 600 police teams and volunteers were deployed at intersections to hand out fines of nearly 4,000 rupees ($60; €54) to anyone breaking the new rules.

Experts warn the car restrictions won't be enough to tackle the problem. "If air pollution was solely due to the vehicular traffic, then this would be a solution," climate policy analyst Siddharth Singh told Agence France-Presse. "Right now it cannot be a solution because motorized private transport has a very small share in the whole pie."

Not everyone has heeded warnings from authorities to stay indoors. Delhi locals are no strangers to high levels of pollution, and many simply went about their lives as as usual. India has 10 of the world's most polluted cities, according to the World Health Organization.
