Dramatic developments overnight on the occupation of the Malheur National Wildlife Refuge by armed militants, as one of the occupiers was killed during a traffic stop and eight more, including the group's leader Ammon Bundy, were arrested. The AP has a full report here. The group, which has included people from as far away as Arizona and Michigan, seized the refuge headquarters on Jan. 2.

Arizona rancher Robert "LaVoy" Finicum, was the man killed, the Oregonian reported. The 55-year-old was a frequent and public presence at the refuge, often speaking for the group at news conferences. Jason Patrick, one of the leaders of the occupation, told Oregon Public Broadcasting that five or six group members remain inside the refuge.

In addition to Ammon Bundy, those arrested were: his brother Ryan Bundy, 43; Brian Cavalier, 44; Shawna Cox, 59; and Ryan Payne, 32 - apprehended during the traffic stop on U.S. Highway 395 Tuesday afternoon. Authorities said two others — Joseph Donald O'Shaughnessy, 45, and Peter Santilli, 50 — were arrested separately in Burns, while FBI agents in Arizona arrested another, Jon Eric Ritzheimer, 32. Each will face a federal felony charge of conspiracy to impede officers of the United States from discharging their official duties through the use of force, intimidation or threats, authorities said.
