MOSCOW — Nearly 1,000 people have sought help for injuries caused by a meteor that exploded in the sky, blasting out countless windows, a Russian health official says.

About 985 people asked for medical assistance, Chelyabinsk health chief Marina Moskvicheva, said Friday.

The Interfax news agency quoted her as saying 43 were hospitalized.

The meteor — estimated to be about 10 tons — entered the Earth’s atmosphere going at least 54,000 kph (33,000 mph), the Russian Academy of Sciences said. It shattered about 30-50 kilometers (18-32 miles) above the ground, releasing several kilotons of energy above the Ural Mountains.

Amateur video broadcast on Russian television showed an object speeding across the sky just after sunrise, leaving a thick white contrail and an intense flash.
