Residents began fleeing Moscow Saturday as the worst smog in living memory smothered the city and forced people to don protective masks against pollution over six times higher than safe levels. The wildfires which have sparked the smog were still spreading in central Russia, with 290 new fires in the last 24 hours as weather forecasters said Russia's worst heatwave in decades would continue for the next days.
Moscow landmarks including the Kremlin and golden church cupolas disappeared behind a layer of smoke as many Muscovities remaining in the city wore protective masks or simply clutched wet rags to their faces. Drivers put on their headlights in broad daylight to see through the acrid haze blanketing the capital while the sun appeared as a hazy disc easily viewed by the naked eye with little discomfort.
The smoke - easily visible from space in NASA images - penetrated into homes and offices and was even detected inside the Moscow metro, one of the deepest underground systems in the world. "The situation is truly extreme. People are in circumstances under which they should not have to live," leading Russian doctor Ivan Yurlov of the League for the Nation's Health group told the Kommersant daily.
With health experts warning that the best solution was to leave the city for the weekend, package tours abroad were completely sold out and there was a rush for seats on trains and planes out of the capital, news agencies said. But travellers faced chaos as flights from Domodedovo, one of Moscow's main international airports, and Vnukovo airport to the south-west of the capital were disrupted by the smog with flights diverted to other airports.
Dozens of flights were delayed and around 40 flights cancelled, state aviation committee Rosavitsia said. "It's hellish, all the flights are delayed or cancelled. There are thousands of passengers waiting in the heat and smog and the air conditioning isn't working," a passenger trying to flee via Domodedovo told AFP by telephone.
The other main international hub, Sheremetyevo in the north of Moscow, was working normally. State air pollution monitoring service Mosekomonitoring said that carbon monoxide levels in the Moscow air were now 6.6 times higher than acceptable levels.
Tiny invisible particles from the fires were also present in concentrations 2.2 times higher than norm, with specialists warning these could prove highly dangerous if they entered the human system. Around 7,000 troops were helping fight the fires, the defence ministry said, adding that the situation "remains difficult" in the Kolomna district near Moscow where an anti-missile alert centre is based.
The authorities were also closely watching the situation around the region of Bryansk in western Russia where the soil is still contaminated by the 1986 Chernobyl nuclear disaster. The situation with the wildfires that have sparked the smog showed no sign of abating, with blazes with an area of 193,500 hectares (478,000 acres) recorded across the country. President Dmitry Medvedev meanwhile opened a fund to help the victims of the fires, putting in 350,000 rubles (12,000 dollars) of his own money as an initial donation.
