Two men in the US accused of planning to build a "death ray" to target enemies of Israel have been charged.
Glendon Scott Crawford, 49 and Eric Feight, 54, from upstate New York were due to appear before a federal court on terrorism charges today, the New York Daily News reports.
Authorities alleged one of the men, who worked for General Electric, had tried to build a "mobile, remotely operated, radiation-emitting device" to target victims with lethal doses of radiation.
FBI agents claim Crawford described himself as a member of the Ku Klux Klan.
The Times Union reports that the FBI used undercover informants posing as South Carolina businessmen with Klan sympathies in order to get in contact with Crawford.
Each of the men face up to 15 years in jail and a $270,000 fine if convicted.
A death ray is believed to remain a theoretical weapon that was first conceptualised in the 1920s.
A number of inventors have said they have made a death ray but their claims remain unproven.
Law enforcement officials became aware of the men's alleged plans in April 2012 after they approached Jewish organisations to seek funding for the project.
While under investigation the men allegedly built the device but federal officials said it was "rendered inoperable at all times" and did not pose a threat to the public.
