A man suspected of planning to attack a Missouri hospital was killed during a shootout with F.B.I. agents, the authorities said on Wednesday.
The deadly encounter took place on Tuesday afternoon in suburban Belton, Mo., after agents on a tactical team tried to arrest the man as part of a domestic terrorism investigation.
It was not clear whether the man was killed by F.B.I. agents or died by suicide. He was taken to a hospital, where he was pronounced dead. Officials identified the man as Timothy R. Wilson, 36.
According to officials, Mr. Wilson had expressed racist and anti-government sentiments. He had been under F.B.I. scrutiny since September, and the authorities said that at one point he had considered attacking multiple targets, including a school with a large number of black students, as well as a mosque and a synagogue.
“Wilson considered various targets and ultimately settled on an area hospital in an attempt to harm many people, targeting a facility that is providing critical medical care in today’s environment,” the F.B.I. said in a statement.
Last week, Belton’s mayor issued a stay-at-home order for its residents. Authorities said Mr. Wilson said he felt compelled to act because of the mayor’s order and intended to use a car bomb to cause mass casualties at the hospital.
