Federal land managers confirmed they released all 400 head of cattle rounded up on public land in southern Nevada from a rancher who has refused to recognize their authority.
The Bureau of Land Management took the action Saturday afternoon after hundreds of states' rights protesters, including militia members, showed up at corrals outside Mesquite to demand the animals' return to rancher Cliven Bundy.
The fight has widened into a debate about states' rights and federal land-use policy. The agency revoked Cliven Bundy's grazing rights after he stopped paying grazing fees and disregarded court orders to remove his animals.
The bureau issued a brief statement saying the cattle were released "due to escalating tensions."
The release also came only hours after the bureau announced an abrupt halt to the weeklong roundup because of safety concerns for its employees and the public.
