Defense attorneys are seeking no more than a nine-year prison term for a Chicago businessman convicted of supporting a terrorist group that staged attacks in 2008 on Mumbai, India.

A defense filing before Tahawwur Rana's sentencing Thursday describes him as charitable and kind-hearted. It says he was duped into participation by a manipulative childhood friend, David Coleman Headley.

Prosecutors are asking a federal judge in Chicago to impose the maximum 30-year sentence.

Jurors in 2011 convicted Rana of supporting a never-carried-out plot to attack a Danish newspaper that printed cartoons of the Prophet Muhammad and for supporting the group that attacked Mumbai, killing more than 160 people.

Headley has pleaded guilty to laying the groundwork for the Mumbai attacks and testified against Rana.
