A US government agency has said it has disrupted a plot to assassinate Democratic presidential hopeful Barack Obama.
Authorities have arrested two men for threatening to launch a “killing spree” in the state of Tennessee.
The agency said the alleged attack also threatened to either shoot or decapitate 102 black people.
Agents said they broke up plans by two “neo-Nazi skinheads” to rob a gun store and threaten a predominantly African-American high school, unsealed court records have revealed.
The records did not specify which school was alleged to be threatened.
US correspondent Ian Woods in Washington, said the youth's alleged threat following the release of court records “does not make it a credible threat” to Mr Obama's life.
Jim Cavanaugh, special agent in charge of the Nashville field office for the Bureau of Alcohol, Tobacco, Firearms and Explosives, said the two men planned to shoot 88 black people and decapitate another 14.
The numbers 88 and 14 are symbolic in the white supremacist community.
Cavanaugh said that the men also sought to go on a national killing spree, with Obama as their final target.
Woods said: “It is not necessarily a credible threat to the senator's life. But eight days before an election, clearly something like this will be taken very seriously.”
The US government disrupted an unrelated alleged plot during the Democratic Party Convention in Denver, Colorado, in September.
