The United States said on Monday that it is playing its part in the Indian effort to bring to justice all those who were responsible for terrorist attack in Mumbai in November 2008.

"We have been doing what we can to share information and support the Indian efforts to bring folks to justice," State Department spokesperson Victoria Nuland told mediapersons.

Responding to a question, Nuland said the US is aware of the reports that one of the suspected planners of the 2008 terrorist attacks on Mumbai has been arrested.

"We have a strong interest, as we've said since the day of the attack, in the arrests, prosecution and conviction of all those responsible for the 2008 Mumbai attack, because our own citizens were among the victims. So we want to see all of them brought to justice," she said.

The spokesperson said the US would continue to make the Mumbai attacks accused -- David Headley and Tahawwur Rana -- available to India as appropriate.

"We have routinely provided access to David Headley when asked. And we will continue to make him available as appropriate," she said when asked about the request in this regard from External Affairs Minister S M Krishna, who was in Washington early this month for the third India-US strategic dialogue.
