Enhanced co-operation between India and US on tackling terrorism particularly in South Asia and Pakistan's role in the region, dominated the deliberations of the Union Home Minister P Chidambaram with top officials of Obama Administration today.

Pakistan's role regarding its action against the perpetrators of 26/11 is believed to have come up prominently when Chidambaram met the National Security Advisor General James Jones at the White House. Jones was recently in India and has been in favour of enhanced cooperation between the two countries in counter-terrorism operations and measures.
