Washington state wildlife officials say genetic tests have confirmed that two animals captured last Friday in western Okanogan County are wild, gray wolves.

Before releasing the wolves - a male and a female - biologists fitted them with radio collars to track their movements.

The state Fish and Wildlife Department also noted that a remote camera operated by a private group has photographed the radio-collared male wolf at a location where six pups were also photographed.

Wildlife officials say this is the first documented resident wolf pack in Washington since the 1930s. Wolves are considered endangered in the state. (AP)
