BURNS, Ore. — The last four armed occupiers of a national wildlife refuge in eastern Oregon said they would turn themselves in Thursday morning after law officers surrounded them in a tense standoff.

The development came as Cliven Bundy — who led a Nevada standoff with federal officers in 2014 and who is also the father of the jailed leader of the Oregon standoff — was arrested in Portland.

The four occupiers yelled at officers to back off and prayed with supporters over an open phone line as the standoff played out on the Internet Wednesday night via a phone line being livestreamed by an acquaintance of occupier David Fry.

Fry, 27, of Blanchester, Ohio, sounded increasingly unraveled as he continually yelled, at times hysterically, at what he said was an FBI negotiator. “You’re going to hell. Kill me. Get it over with,” he said. “We’re innocent people camping at a public facility, and you’re going to murder us.”

“The only way we’re leaving here is dead or without charges,” Fry said, who told the FBI to “get the hell out of Oregon.”

Fry and the three others are the last remnants of a group led by Ammon Bundy that seized the Malheur National Wildlife Refuge on Jan. 2 to oppose federal land-use policies. The three others are Jeff Banta, 46, of Elko, Nevada; and married couple Sean Anderson, 48, and Sandy Anderson, 47, of Riggins, Idaho.

Fry said Wednesday the group was surrounded by armored vehicles.

Cliven Bundy, the father of occupation leader Ammon Bundy, flew into Portland International Airport Wednesday night and was arrested by authorities. He was booked into the lockup just before 11 p.m. according to Multnomah County Jail records.

The 74-year-old Nevadan was at the center of the standoff with federal officials over use of public lands. The Oregonian reports he now faces a conspiracy charge of interfering with a federal officer related to that standoff at his ranch.

The FBI confirmed Cliven Bundy’s was taken into federal custody but declined to provide a reason or other details, saying further information would be released by the U.S. Attorney’s office in Las Vegas, which did not respond to a phone call early Thursday.

Ammon Bundy had been demanding that the Oregon refuge be handed over to locals.

A Nevada legislator, Michele Fiore, called the occupiers earlier in the evening to try to get the occupiers to calm down. Fiore said she could help them only if they stayed alive.

“I need you guys alive,” said the Republican member of the Nevada Assembly who was in Portland earlier in the day to show support for Ammon Bundy, who remains jailed. Fiore told occupiers Wednesday night she was driving to the refuge to try to help negotiate their exit from the refuge. The occupiers prayed with Fiore and others as the situation dragged on for hours Wednesday night.
