Prosecutors are asking a federal judge to give the maximum 30-year sentence to a Chicago businessman convicted of supporting a terrorist group that staged the deadly 2008 attacks on Mumbai, India.

U.S. prosecutors made the request in a filing Monday evening in the case of Tahawwur Rana (tuh-HOW'-ur RAH'-nah). Rana was convicted in 2011 of aiding terrorism in Denmark and aiding a terrorist group that staged the India attacks that left more than 160 people dead.

Jurors 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 Pakistani group. They cleared him of involvement in that group's attack on Mumbai.

Rana is to be sentenced in Chicago on Thursday.
