A federal jury has convicted a Bosnian-born man of attempting to bomb New York City's subway in 2009 for al-Qaida.

Adis Medunjanin faces life in prison when he is sentenced on September 7.

The jury found him guilty of nine counts of terrorism, including plotting to kill American soldiers in Afghanistan and consorting with al-Qaida.

Medunjanin's attorneys told the court that he backed out of the plot to set off bombs in the country's busiest subway system. They admit he traveled to Pakistan to join the Taliban, but said he had no intention to cause death and destruction in New York.

But federal prosecutors argued that Medunjanin and two co-defendants trained at an al-Qaida camp where they were asked to carry out a suicide bombing in the United States.

Other targets they looked at included the New York Stock Exchange, Grand Central Terminal, and Times Square.

The two other defendants have already pled guilty and are cooperating with the government awaiting sentence.
