Four armed occupiers are still holed up at a national wildlife preserve in Oregon, the FBI says.
Bureau spokeswoman Beth Anne Steele said “nothing at all” happened overnight at the Malheur National Wildlife Refuge, and she would not discuss any strategic decisions planned for Friday.
The three men and one woman have refused to leave without assurances they will not be arrested.
Authorities have apprehended 11 other activists, including group leader Ammon Bundy, and have fatally shot another during a traffic stop.
The group came to Oregon to protest federal land restrictions and the prison sentences of two local ranchers convicted of setting fires.
