The Russian Academy of Sciences said in a statement hours after the Friday morning fall that the meteor entered the Earth's atmosphere at a speed of at least 54,000 kph (33,000 mph) and shattered about 30-50 kilometers (18-32 miles) above ground. The fall caused explosions that broke glass over a wide area. (AP Photo/ Yevgenia Yemelyanova, Chelyabinsk.ru)The Associated Press

CHELYABINSK, Russia – A small army of workers is laboring to replace the estimated 200,000 square meters (50 acres) of windows shattered by the shock wave from a meteor that exploded over Russia's Chelyabinsk region.
The astonishing Friday morning event blew out windows in more than 4,000 buildings in the region, mostly in the capital city of the same name and injured some 1,200 people, largely with cuts from the flying glass.
Fifty of them remain hospitalized, but their injuries are reported to be not life-threatening.
Regional governor Mikhail Yurevich on Saturday said damage from the explosion is estimated at 1 billion rubles ($33 million).
