A former leader of the local Shia Muslim community has been convicted in the United States of taking part in a failed plot to blow up fuel tanks and pipelines at JFK airport in New York.
Kareem Ibrahim was convicted of five conspiracy counts in the plot, which officials say was meant to outdo 9/11.
Russell Defreitas and Abdul Kadir are serving life sentences after also being convicted for their roles.
Ibrahim, 65, also faces life in prison.
His sentencing is due on 21 October.
Prosecutors said the men had wanted to kill thousands in New York and shake the US economy by blowing up fuel tanks and pipelines that run under a neighbourhood near the airport.
The scheme was uncovered when an informant recorded a discussion about the planned attack between Kadir and Defreitas, who began preparations for the attack in 2006.
Defreitas, a 68-year-old former cargo handler, and Kadir, a former member of Guyana’s parliament, were convicted on conspiracy charges in August 2010.
