A Berlin zookeeper was crushed to death by a several-hundred kilogram musk ox after the keeper forgot to close a security enclosure.
The woman, whose name was not released, was feeding the musk ox when it came through a gate that should have been shut to isolate the area from the main pen, said Bernhard Blaszkiewitz, director of Berlin's Tierpark.
