A hunter has been injured after being attacked by a bear in Grand Teton National Park.

Officials said Sunday the 32-year-old Jackson man followed safety recommendations for handling such an encounter, including carrying bear spray and dropping to the ground and covering his head. The hunter did not fire any shots at the bear and he had not killed any elk.
Park rangers say warning signs have been placed in the area.

Authorities are investigating the incident, but say many details remain unclear, including what species of bear was involved or whether this was a defensive or predatory encounter.

Officials have not released the hunter's name, and say it is too early to tell the extent of his injuries.
