Grizzly bear seriously injures man in Wyoming’s Grand Teton national park

Also on Sunday, in Alaska, a man was killed as he tried to photograph newborn moose calves when their mother attacked

A grizzly bear attacked and seriously injured a man in western Wyoming's Grand Teton national park, prompting closure to the public of a mountain there on Monday.

That mauling was one of at least two serious animal attacks on people in the US wilderness on Sunday. Elsewhere, in Alaska, a 70-year-old man who was attempting to take photos of newborn moose calves was attacked and killed by their mother, authorities said.
