An aerial meteorite explosion has wreaked havoc in Russia’s Urals. The blast caused widespread panic, damaged buildings, blew out thousands of windows and lead hundreds to seek medical attention for minor injuries.

­The incident was caused by a bolide, scientists said. Multiple dashboard videos appeared online, showing huge fireballs flying over buildings and exploding with a strong blast as the meteriote broke into pieces mid-air. A local zinc factory was the worst-hit, with some of its walls collapsed.

18:40 GMT: The search for the meteorite parts at Chebarkul Lake and at other two locations has officially been stopped. The huge ice hole found at the lake on Friday “has formed because of a different reason,” the Vice-Governor of Chelyabinsk region Igor Murog told Interfax-Ural.

13:32 GMT: Officials will take out bank loans to pay for repairs to meteorite damage, Chelyabinsk regional Governor Mikhail Yurevich said. He also asked for at least 500 million rubles in repairs to be subsidized by the federal government.

­12:30 GMT: Chelyabinsk municipal medical services have released official figures on the number of injured: 1158 people applied for medical assistance, including 289 children. Fifty-two people were hospitalized, including 13 children. Several people with light injuries have been already released from hospitals.

­12:14 GMT: Repair work in Chelyabinsk will be completed in three days, Russian Emergency Minister Vladimir Puchkov said, adding that basic utilities such as power, transport and telephone lines are functioning normally. The Minister ordered that 122 buildings be inspected for damage. Some 24,000 people and 3,500 machines are engaged in the city recovery effort.

­12:10 GMT: Chelyabinsk Governor Mikhail Yurevich described February 15 as the city’s second birthday: “If the meteor, which exploded above us, was just a little bigger, it’s hard to imagine what could have happened to our towns and villages. The huge sum of 1 billion rubles needed to repair broken windows and damaged walls pales beside losses we could have had. The most important thing is that nobody died!”

­07:58 GMT: No meteorite fragments were found at the bottom of Chebarkul Lake, says the Emergencies Ministry. A lack of underwater visibility, as well as a thick – up to 1.5 meters – layer of ooze were cited as the main reasons for failure. Six divers spent three hours searching for solid objects in the mud but finally gave up. Water samples taken from the lake have also shown nothing unusual.

­06:46 GMT: About 200,000 square meters of window glass in Chelyabinsk were shattered by the meteorite explosion, Russia’s Emergency Ministry reports.

The broken windows at all medical institutions and about a third of the other buildings have already been repaired. By Monday, all schools and kindergartens are expected to resume normal operations.

­05:59 GMT: Infrasound stations tracking nuclear tests worldwide recorded the meteorite explosion above the Chelyabinsk region. Eleven stations of the 45 belonging to the Comprehensive Nuclear-Test-Ban Treaty Organization determined that the incident in Russia took place at 03:22 GMT on Friday. The stations are located in 35 countries around the world.

05:26 GMT: Russia’s Emergency Ministry has finalized the number of people injured by the meteorite explosion: 1,145 have sought medical attention, 50 of whom remain in hospital. No deaths from the incident have been officially registered, the Ministry reports.

­04:55 GMT: The meteorite explosion above the Chelyabinsk region has damaged 100,000 households, with total damages exceeding 1 billion rubles (about $33 million), the regional governor announced. “That’s not much for such an accident,” Governor Mikhail Yurevich said, adding that up to 30 percent of the smashed windows have already been replaced, and promising to repair the rest within a week.

04:10 GMT: Six divers have started searching for meteorite fragments on the bottom of Chebarkul Lake near Chelyabinsk. The search will continue for about four hours; nothing has been found so far.

­03:19 GMT: Medics in the Chelyabinsk region report that 51 persons remain in hospital as a result of the meteorite explosion, 13 of whom are children. One woman with a severe spinal fracture has been taken to Moscow by a ‘flying hospital’ aircraft, sent to Chelyabinsk by the Emergency Ministry. Most of the injured will be discharged from hospital in a matter of days, but still there are people with serious wounds – some fingers and toes were reportedly amputated, while others suffer from severe post-traumatic stress disorder.

­15:42 GMT: NASA said that the Chelyabinsk fireball had nothing to do with the approaching 2012 DA14 asteroid, as some scientists had previously suggested.

"The trajectory of the Russian meteorite was significantly different than the trajectory of the asteroid 2012 DA14, making it a completely unrelated object,” the space agency said on its website. “In videos of the meteor, it is seen to pass from left to right in front of the rising sun, which means it was traveling from north to south. Asteroid DA14's trajectory is in the opposite direction, from south to north."
