US police say they have arrested the leader of an armed militia which occupied a wildlife refuge in Oregon, with one person killed in a shoot-out.
Ammon Bundy and five others were arrested during a traffic stop, police said. One person was injured.
It is not clear whether the police operation brought the standoff at the wildlife refuge to an end.
The self-proclaimed militia led by Mr Bundy occupied the refuge earlier this month in support of two local ranchers.
FBI officials said in a statement that Mr Bundy, 40, was arrested along with his brother Ryan Bundy, 43, Bryan Cavalier, 44, Shawna Cox, 59, and Ryan Walen Payne, 32, on Tuesday afternoon on highway 225.
In a separate incident, Joseph Donald O’Shaughnessy, 45, another activist, was arrested in Burns, Oregon.
The FBI said it conducted with Oregon State Police an “enforcement action to bring into custody a number of individuals associated with the armed occupation of the Malheur National Wildlife Refuge”.
“One individual who was a subject of a federal probable cause arrest is deceased. We will not be releasing any information about that person pending identification by the medical examiner’s office,” the FBI said.
It added: “One individual suffered non-life threatening injuries and was transported to a local hospital for treatment. He was arrested and is currently in custody.”
Mr Bundy and a right-wing militia group occupied the refuge on 2 January to protest against the imprisonment of two ranchers in rural Harney County.
