In his first reaction to the sentencing of the 52-year- old Pakistan-American terrorist, External Affairs Minister Salman Khurshid said New Delhi is "disappointed" since "we wanted him to be tried here in India".
However, he added, that India has full faith in the US legal system.
"If the trial would have been held here, the punishment would have been tougher...We will still try and get him tried in India," Khurshid told reporters here.
He also said India will try and push for Headley's extradition.
"Since we are the ones who lost lives, this is why it would have been better if the trial was held here, but there is a legal system in the US, that we know, and we will still try and hope that he will be extradited," he said.
Headley was awarded 35 years imprisonment by a US court followed by five years of supervised release for his role in plotting the 26/11 Mumbai carnage.
