The standoff by an anti-government group in Oregon has taken a violent turn: News reports say that one person is dead and group leader Ammon Bundy is in custody along with at least five of his supporters. It's not clear yet what happened, but CNN reports that police detained Bundy and others at a traffic stop. Gunfire reportedly broke out during the stop, though it's not known which side fired first. The AP reports that one person—apparently one of Bundy's supporters but not Bundy himself—is dead. Police closed off a 56-mile stretch of US 395 between the towns of Burns and John Day, reports the Oregonian. Bundy's group has been holed up in the Malheur National Wildlife Refuge since Jan. 2 to protest federal land policies. Also unclear is whether others still at the refuge will try to stay there.
