A Ukrainian official says a bear fatally mauled a woman who wandered into its cage on an animal farm.

Regional emergency official Olexandr Soldatov says the middle-aged woman may have been drunk when she stepped into the cage Monday on a farm outside the eastern city of Donetsk.

He says one of the two bears inside the cage then attacked the woman.

He said Tuesday that officials were trying to figure out how she got into the cage unnoticed.

There have been a number of cases of animal attacks involving intoxicated zoo and farm visitors in Ukraine, where safety rules are often neglected.
