New Delhi orders construction halt as pollution levels soar

The government's Central Pollution Control Board rated the city's air quality Friday as "severe" — the worst possible category — for the fourth day in a row.
New Delhi's level of PM2.5, tiny particulate matter that can dangerously clog lungs, exceeded 170 Friday morning, more than six times higher than the World Health Organization considers safe.
The order to halt construction, which was issued Thursday night, came amid days of winds that have carried dirt and dust across northern India, causing pollution to spike in numerous cities and forcing dozens of flight cancellations.
