• MOSCOW (AP) -- A meteor that scientists estimate weighed 10 tons (11 tons) streaked at supersonic speed over Russia's Ural Mountains on Friday, setting off blasts that injured some 500 people and frightened countless more.
• The Russian Academy of Sciences said in a statement that the meteor over the Chelyabinsk region 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. The Emergency Ministry says more than 500 people sought treatment after the blasts and that 34 of them were hospitalized.
• "There was panic. People had no idea what was happening. Everyone was going around to people's houses to check if they were OK," said Sergey Hametov, a resident of Chelyabinsk, about 1500 kilometers (930 miles) east of Moscow, the biggest city in the affected region.
• "We saw a big burst of light then went outside to see what it was and we heard a really loud thundering sound," he told The Associated Press by telephone.
• Another Chelyabinsk resident, Valya Kazakov, said some elderly women in his neighborhood started crying out that the world was ending.
• Some fragments fell in a reservoir outside the town of Cherbakul, the regional governor's office said, according to the ITAR-Tass news agency. It was not immediately clear if any people were struck by fragments.
• The agency also cited military spokesman Yarslavl Roshupkin as saying that a six-meter-wide (20-foot-wide) crater was found in the same area which could be the result of fragments striking the ground.
• Meteors typically cause sizeable sonic booms when they enter the atmosphere because they are traveling much faster than the speed of sound. Injuries on the scale reported Friday, however, are extraordinarily rare.
• Interior Ministry spokesman Vadim Kolesnikov said that about 600 square meters (6000 square feet) of a roof at a zinc factory had collapsed. There was no immediate clarification of whether the collapse was caused by meteorites or by a shock wave from one of the explosions.
• Reports conflicted on what exactly happened in the clear skies. A spokeswoman for the Emergency Ministry, Irina Rossius, told The Associated Press that there was a meteor shower, but another ministry spokeswoman, Elena Smirnikh, was quoted
