Pakistan-born Chicago businessman Tahawwur Rana was found guilty on Thursday by a U.S. jury of supporting an Islamic militant group blamed for the 2008 attack in Mumbai that killed 166 people.

In the trial, held in U.S. federal court in Chicago, the 50-year-old former Pakistani Army doctor with Canadian citizenship was also found guilty of conspiring to attack a Danish newspaper, Jyllands-Posten, which published cartoons lampooning the Muslim Prophet Mohammed, and behead its staff. However, the plot was never carried out, said a Reuters' report.

Rana was charged with three counts of providing material support for terrorism.

Rana's childhood friend David Headley, the key witness, said Rana had provided help as he scouted targets in India. Headley also witness implicated Pakistan's intelligence agency, ISI, in the Mumbai attack.

50-year-old Headley, an American with a Pakistani father, related how he plotted the Mumbai attack with his handlers from the militant group Lashkar-e-Taiba.

On the other hand, the defense argued Headley was lying. He had pleaded guilty and promised to testify in exchange for avoiding the death penalty and extradition to India, Pakistan or Denmark.
