In one affected Russian region, Chelyabinsk, the authorities have received numerous calls reporting injuries received as a result of the meteorite shower, and 20,000 emergency response workers have been mobilized. Background radiation levels reportedly remain unchanged.

Reports vary about whether this was one larger meteorite, or many smaller ones.

Russian Prime Minister Dmitry Medvedev, speaking at the economic forum held in the neighboring Krasnoyarsk region, called the meteorite fall “a symbol of the forum.”

“I hope that there will be no serious consequences, but it is a demonstration that it is not only the economy that is vulnerable, but our planet as well,” he said.

Russia's nuclear agency, Rosatom, issued a statement saying its facilities across affected regions were functioning normally.
