Witnesses said that houses shuddered, windows were blown out and cellphones stopped working. Atmospheric phenomena have been registered in the cities of Chelyabinsk, Yekaterinburg and Tyumen. In Chelyabinsk, witnesses said the explosion was so loud that it resembled an earthquake and thunder 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 enacted the ‘Fortress’ plan in order to protect vital infrastructure. Office buildings in downtown Chelyabinsk are being evacuated. Injuries were reported at one of the city’s secondary schools, supposedly from smashed windows. No other injuries have been reported so far. An emergency message published on the website of the Chelyabinsk regional authority urged residents to pick up their children from school and remain at home if possible. The regional Emergency Ministry said the phenomenon was a meteorite shower, but locals have speculated that it was a military fighter jet crash or a missile explosion. “According to preliminary data, the flashes seen over the Urals were caused by [a] meteorite shower," the Emergency Ministry told Itar-Tass news agency. Many locals reported that the explosion rattled their houses and smashed windows. “This explosion, my ears popped, windows were smashed… phone doesn’t work,” Evgeniya Gabun wrote on Twitter. “My window smashed, I am all shaking! Everybody says, that a plane crashed,” Twitter user Katya Grechannikova reported. Many speculated on what caused the powerful explosion – some claimed it was a crashed plane, while others said it could have been a UFO. “My windows were not smashed, but I first thought that my house is being dismantled, then I thought it was a UFO, and my eventual thought was an earthquake,” Bukreeva Olga wrote on Twitter.
