Russian divers Wednesday pulled from a murky lake in the Urals a half-tonne suspected meteorite said to have been part of a meteor whose ground-shaking shockwave hurt 1,200 people in February.

The dramatic recovery operation came eight months after a piercing streak of light lit up the morning sky in the central Russian region of Chelyabinsk in scenes some locals said made them think of the onset of a nuclear war.

The meteor broke up into myriad pieces—some no bigger than the size of a fingernail—that scientists are still finding across the remote region to this day.

Much of the debris landed in a local lake called Chebarkul that the divers entered on Wednesday in an operation covered live on national television.

Broadcasts showed a team pull out a 1.5-metre-long (five-foot-long) rock from the lake after first wrapping it in a special casing while it was still underwater.

The boulder was then pulled ashore and placed on top of a massive scale for the all-important weighing—an operation that quickly went partially wrong.
