7:35 a.m.

The FBI has established checkpoints around a national wildlife preserve in Oregon where some armed activists still are believed to be holed up, saying the decision came out of "an abundance of caution."

Authorities arrested the leaders of the small group that has been occupying Malheur National Wildlife Refuge for more than three weeks during a traffic stop where gunfire erupted and one man was killed late Tuesday.

Jason Patrick, a new leader of the occupation, told Oregon Public Broadcasting that five or six members of the group agreed to continue the standoff.

The FBI said early Wednesday that anyone leaving the refuge will have to show identification and submit to a vehicle search. Only ranchers who live in the area surrounding the preserve will be allowed to pass the checkpoints.

UPDATE: Arianna Finicum told the Oregonian newspaper that her father, Robert LaVoy Finicum, was killed. Authorities have said only that an adult male was killed

BURNS, Ore. (AP) — The leaders of an armed group that's occupied a national wildlife refuge in Oregon for the past three weeks are under arrest.

Militant leader Ammon Bundy and his followers were reportedly heading to a community meeting Tuesday afternoon when they were stopped by FBI agents.

Bundy, his brother and three others were taken into custody. Three others were arrested separately. Another person was shot and killed by an officer. The Oregonian newspaper identifies him as an Arizona rancher.
