A meteor streaked across the sky above Russia's Ural Mountains today morning, causing sharp explosions and injuring more than 400 people, many of them hurt by broken glass.

"There was panic. People had no idea what was happening. Everyone was going around to people's houses to check if they were okay," said Sergey Hametov, a resident of Chelyabinsk, about 1500 kilometers east of Moscow, the biggest city in the affected region.u00a0
