UPDATE: The Russian Academy of Sciences is estimating the meteor that streaked into the skies over the Ural Mountains and caused shock waves that injured more than 400 people weighed about 10 tons.
The academy said in a statement hours after the Friday morning fall that the meteor entered the Earth's atmosphere at a speed of at least 33,000 mph and shattered about 32 miles above ground. The fall caused explosions that broke glass over a wide area.
The Emergency Ministry says more than 500 people sought treatment after the blasts and that 34 of them were hospitalized
Fragments of the meteor fell in a thinly populated area of the Chelyabinsk region, the Emergency Ministry said in a statement. Interior Ministry spokesman Vadim Kolesnikov said more than 400 people had sought medical treatment after the blasts, and at least three had been hospitalized in serious condition.
Many of the injuries were from glass broken by the explosions.
