A Bosnian-born US citizen has been convicted over a New York suicide-bomb plot and could face a life sentence.
Adis Medunjanin and two former schoolmates planned to bomb the New York subway before the 9/11 terror attacks anniversary in 2009.
The men were trained by al-Qaeda in Pakistan before agreeing to participate in the plot, prosecutors said.
Defence lawyers argued that US agents unfairly coerced Medunjanin and intimidated his family.
The prosecution included the testimony of four men: Najibullah Zazi, who admitted masterminding the plot, and Zarein Ahmedzay, who were both at high school with Medunjanin.
They told the court that they had considered targeting the New York Stock Exchange, Times Square and Grand Central Terminal.
Zazi testified that they targeted New York's subway trains at rush hour because it was "the heart of everything in New York City".
He said he had learned to distill ingredients for explosives from products such as nail varnish remover that are sold at pharmacies.
The court also heard from Saajid Badat, a British man who plotted to blow up a plane with a shoe bomb, and a man from Long Island, New York, who had advised al-Qaeda on how to target a Walmart shop.
In a video recording played out during the trial, Badat described a meeting with Osama Bin Laden.
He told the court that the al-Qaeda leader had said: "The American economy is like a chain. If you break one - one link of the chain - the whole economy will be brought down."
Badat added that the failed plot he had been involved with was intended to hit the US aviation industry, and the wider economy.
Medunjanin is to be sentenced on 7 September.
