News: Polar Bear Knut dies at Berlin Zoo

Germany is a nation in mourning after the sudden death of Knut, Berlin's world-famous polar bear. 

Knut was pulled from a pool in his enclosure dead after he fell in and drowned. His leg was apparently shaking and he fell in and couldn't swim. 

He was just 4 years old and suffered a very premature death, the average life expectancy for a polar bear is 35. Vets are due to conduct an autopsy today. 

This is a very tragic loss. Knut was abandoned by his mother and brought in to the Berlin Zoo where he was brought up by humans. His main care taker and true friend suffered a heart attack a few years ago.
