India says it is disappointed with the sentence a Pakistani-American man given in a U.S. court for his role in the 2008 Mumbai terror attacks.
External Affairs Minister Salman Khurshid said Friday David Coleman Headley deserves more than the 35-year prison sentence handed down Thursday in Chicago's federal court.
India had sought to have Headley extradited to face trial in India for his role in the attacks.
Headley could have received life in prison, but U.S. federal prosecutors asked for a lighter sentence because he provided information that led to charges against other people involved with the Pakistani terrorist group Lashkar-e-Taiba.
In November 2008, Lashkar terrorists took over a hotel, a Jewish center and other buildings in Mumbai for three days. The attack killed 166 people, including six Americans.
Headley said he scouted locations for other possible attacks and received training from Pakistan's intelligence service.
Headley also said he received weapons and other training from Lashkar-e-Taiba, which he says also coordinated with Pakistani intelligence.
Pakistan's powerful Inter-Services Intelligence agency has long been suspected of involvement in the Mumbai attacks, and three ISI agents were named as co-conspirators by U.S. prosecutors. Headley testified that the ISI's involvement in the Mumbai plot was limited to a handful of rogue agents.
