FBI officials have established checkpoints around the Malheur National Wildlife Refuge as a handful of armed militants remain inside. 

OPB spoke with the new leaders inside the compound, including Jason Patrick, who said the remaining group of militants are prepared to stay for the long run. Reporter John Sepulvado tweeted from the field:

The children that OPB reported were inside the compound before the standoff are not in the building.

In a press release early Wednesday, FBI officials said any vehicles approaching the established checkpoints will be stopped and searched, and all occupants of the vehicles must present identification.

Law enforcement officials said they will arrest anyone who is not compliant with the checkpoint procedure. The only people allowed to pass the checkpoints will be local ranchers, according to the FBI.

“Anyone coming out of the refuge will have his or her identification confirmed and any associated vehicles searched,” the FBI stated.

The monthlong occupation of an Oregon wildlife refuge took a turn toward a possible conclusion Tuesday night – with the death of militant Robert LaVoy Finicum after an officer involved shooting. At least eight others were arrested, including the leader of the takeover Ammon Bundy.
