The Federal Bureau of Investigation surrounded the national wildlife refuge in Oregon where four right-wing protesters remain on Wednesday evening. Armored vehicles surrounded the buildings where three men and a woman are holed up. The occupiers say they are armed, according to a livestream of the confrontation. The FBI said the encirclement began when David Fry, 27, drove an all-terrain vehicle outside of the encampment. When an agent approached Fry, who is wanted on a federal conspiracy charge, he allegedly fled back to the encampment at a high rate of speed. The FBI said negotiations are on-going and no shots have been fired. "We're leaving tomorrow," Fry said to the FBI. Cliven Bundy, a Nevada rancher and the father of group leader Ammon Bundy, said he is on his way to the refuge. Nevada Assemblywoman Michele Fiore and Ammon Bundy's lawyer, Mike Arnold, also said they were headed to the scene.
