BURNS, Ore. (AP) - The Oregon nature preserve being occupied by an armed anti-government group was surrounded by law-enforcement agents Wednesday, a day after one of the occupiers was killed by officers during a traffic stop and eight others, including group leader Ammon Bundy, were arrested. The confrontation came amid increasing calls for authorities to take action against Bundy for the illegal occupation of the Malheur National Wildlife Refuge, which was seized by the group on Jan. 2 in a bid to force the government to turn federal lands over to local officials. The traffic stop was supposed to bring a peaceful resolution to the situation but ended badly, Harney County Sheriff Dave Ward said, expressing disappointment.
