(BBC News) A big rescue and clean-up operation involving more than 9,000 workers is going on in the Ural mountains following Friday’s meteor strike, Russia’s emergencies ministry says.

President Vladimir Putin ordered the operation to help some 1,200 people who were injured, including 200 children, mostly by shattered glass.

The shockwave damaged an estimated 200,000 sq m (50 acres) of windows.

Russian officials put the cost of the damage at about 1bn rubles ($33m).
