A meteor has fallen over Russia - injuring almost 1000 people and damaging buildings.
Most of those people hurt only suffered minor cuts and bruises but windows were blown out of buildings.
A fireball was seen racing through the sky above the Russian city of Yekaterinburg, followed by loud bangs.
Reports say that the meteor landed in a lake near Chebarkul, a town in the neighbouring Chelyabinsk region.
Thousands of rescue workers have now arrived in the area to provide help.
Officials say fragments falling from a large meteor that partially burned up in the lower atmosphere caused the damage.
Debris also reportedly fell on the west Siberian region of Tyumen.
