At this hour, just after 11pm PT, this story is labeled as "BREAKING NEWS" at Russia's state-owned RT website.
RT is reporting "Up to 100 people sought medical attention as a result of the incident, according to the Russian Interior Ministry. No serious injuries have been reported, with most of the injuries caused by broken glass and minor concussions."
[Update: AP now pegs the number as "more than 400 people" injured, according to a Russian Interior Ministry spokesperson. || Later Update: Washington Post now reports "985 people sought medical help for injuries and 43 were hospitalized."]
But take a look at some of the remarkable video...
Here's the beginning of RT's coverage explaining what seems to be going on...
According to unconfirmed reports, the meteorite was intercepted by an air defense unit at the Urzhumka settlement near Chelyabinsk. A missile salvo reportedly blew the meteorite to pieces at an altitude of 20 kilometers.
A bright flash was seen in the Chelyabinsk, Tyumen and Sverdlovsk regions, Russia’s Republic of Bashkiria and in northern Kazakhstan.
Lifenews tabloid said that at least one piece of the fallen object caused damage on the ground in Chelyabinsk. According to preliminary reports, it crashed into a wall near a zinc factory, disrupting the city's Internet and mobile service.
The Emergency Ministry reported that 20,000 rescue workers are operating in the region. Three aircraft were deployed to survey the area and locate other possible impact locations.
Witnesses said the explosion was so loud that it seemed like an earthquake and thunder had struck at the same time, and that there were huge trails of smoke across the sky. Others reported seeing burning objects fall to earth.
Police in the Chelyabinsk region are reportedly on high alert, and have begun ‘Operation Fortress’ in order to protect vital infrastructure.
This certainly seems like a hoax, but apparently it is not, as U.S. news sites are now picking this up as well. See RT's page for more details.
Here are a few of the photos they have posted, said to have been published by Twitter users, and one possible explanation for what seems to be going on...
