Planes diverted, workers sent home as 1,850-mile cloud descends on capital
MOSCOW — Planes were diverted from Moscow airports on Friday after huge peat and forest fires blanketed the capital in acrid smoke, forcing some businesses to close and office workers to wear surgical masks at their desks.
Pollution surged to five times normal levels in the city of 10.5 million, the highest sustained contamination since Russia's worst heat wave in more than a century began a month ago.
Officials urged Muscovites to not venture outdoors.
"Looking at the overall duration (of the pollution), today's smoke level is the worst yet," said Alexei Popikov, an expert on air quality at Moscow's state-run pollution monitoring agency.
