About 400 people were injured when a meteorite shot across the sky in central Russia today sending fireballs crashing to Earth, smashing windows and setting off car alarms.
Residents on their way to work in Chelyabinsk heard what sounded like an explosion, saw a bright light and then felt a shockwave, according to a Reuters correspondent in the industrial city 1500 km east of Moscow.
The meteorite raced across the horizon, leaving a long white trail in its wake which could be seen as far as 200 km (125 miles) away in Yekaterinburg. Car alarms went off, windows shattered and mobile phones worked only intermittently.
"I was driving to work, it was quite dark, but it suddenly became as bright as if it was day," said Viktor Prokofiev, 36, a resident of Yekaterinburg in the Urals Mountains.
"I felt like I was blinded by headlights," he said.
No fatalities were reported but President Vladimir Putin, who was due to host Finance Ministry officials from the Group of 20 nations in Moscow, and Prime Minister Dmitry Medvedev were informed.
A local ministry official said the meteor shower may have been connected with an asteroid the size of an Olympic swimming pool that was due to pass Earth at a distance of 27,520 km but this could not be confirmed.
Windows were shattered on Chelyabinsk's central Lenin Street and some of the frames of shop fronts buckled.
A loud noise, resembling an explosion, rang out at around 9.20am. The shockwave could be felt in apartment buildings in the industrial city's centre.
"I was standing at a bus stop, seeing off my girlfriend," said Andrei, a local resident who did not give his second name. "Then there was a flash and I saw a trail of smoke across the sky and felt a shockwave that smashed windows."
A wall was damaged at the Chelyabinsk Zinc Plant but there was no environmental threat, a plant spokeswoman said.
