US Central Intelligence Agency chief Leon Panetta made a stopover in New Delhi to discuss security threats in the South Asian region after visiting Pakistan, a report said Saturday.

The CIA chief met India’s Home Secretary G.K. Pillai and senior intelligence officials to discuss regional intelligence worries and security for the Commonwealth Games which open in New Delhi on Sunday, the Press Trust of India reported, quoting unnamed official sources.

Panetta’s visit marked the first high-level visit by a US official since a team of the Indian National Investigation Agency (NIA) had questioned David Headley, who plotted the 2008 Mumbai attacks in which 166 people died, in May in Chicago, the Indian news agency said.

No further details were available.

Indian government officials could not immediately be contacted for comment while the US embassy in New Delhi said it never comments on “intelligence matters.”

Pakistan said Thursday that Panetta had in Islamabad promised to respect the country’s sovereignty and examine reports that NATO helicopters conducted deadly cross-border raids from Afghanistan.
