An ash cloud from a volcano that erupted in Iceland on Wednesday will reach Russian regions to the south of Moscow, the Russian Hydrometeorology and Environmental Monitoring Service said.
"At night, the ashes spread to the Moscow air zone, visibility on the ground and from a height was 10 km," the service said.
"Aircraft crews observed a glow of ash particles in a layer from 800 to 3200 meters. At the moment (daytime), the aircraft crews in the Moscow air zone are not recording any volcanic ash."
The eruption on the Eyjafjallajokull Glacier in Iceland has already paralyzed air traffic in Britain, France, Germany, Belgium, Latvia, Ireland, Poland, Austria and most of the Nordic countries.
The service said that flights from Russia to European countries are delayed.
Krakow airport in Poland was closed earlier on Friday, jeopardizing plans for the funeral of President Lech Kaczynski on Sunday.
Earlier in the day, Russia's Emergencies Ministry said the dust cloud from the volcano in Iceland did not pose a threat to Russia or the Russian people.
According to regional departments of the ministry, ash currently falling in the Arkangelsk, Murmansk and Vologda regions in northwestern Russia is not visible.
Iceland sits on a large volcanic hot spot in the Atlantic's mid-oceanic ridge. The volcano last erupted on March 21. Before that it had been dormant since 1821, when eruptions lasted for two years.
