Mike Coston at Avian Flu Diary has an excellent, detailed report:
Russia: Hundreds Injured By Meteorite Strike. Excerpt:
On the same day that a medium-sized asteroid (2012 DA14) will pass safely by our planet, millions of people in Russia had a brief encounter with a much smaller vagabond of space.
Russian media overnight is reporting that a meteor entered the atmosphere, and broke into several pieces, then crashed into the Russian Urals, near Chelyabinsk.
Three impact sites have been identified, hundreds of people have reportedly been injured, and and a number of buildings have been damaged from the blast effects.
Mike's post includes video from this and other events and several other links.
