From The Guardian where there are more videos:
A meteorite has flared spectacularly in the sky and exploded over the
Russian region of Chelyabinsk, reportedly injuring around 400 people.
Fragments of the meteor fell in a thinly populated area of the region, the emergencies ministry said in a statement.
Interior ministry spokesman Vadim Kolesnikov said 102 people had
called for medical assistance following the incident, mostly for
treatment of injuries from glass broken by the explosions.
Kolesnikov also said about 600 sq metres (6,500 sq ft) of a roof at a zinc factory had collapsed.
