A female moose attacked and killed a man who was attempting to photograph her calves, according to Alaskan officials.

The moose charged at two men who came too close to her offspring in Homer on Sunday morning, Alaska State Troopers said in a statement.

“As they were walking through the brush looking for the moose, that’s when the cow moose attacked,” Austin McDaniel, a spokesperson for the Alaska Department of Public Safety, told the Associated Press on Monday, adding that the moose, who had recently given birth, attacked the men as they were fleeing.
