Top Obama security aide meets Indian PM

US National Security Adviser James Jones, who arrived in New Delhi late Thursday after stops in Afghanistan and Pakistan, met Prime Minister Manmohan Singh and Indian National Security Adviser M.K. Narayanan, a government spokesman told AFP.

No details of the discussions were made available but an Indian government official said: "Pakistan and terrorism emanating from there against India," were the issues on the agenda ahead of the meetings Friday.

Jones' visit comes the day after Defence Minister A.K. Antony reportedly warned a group of senior military commanders that the "turmoil within" Pakistan could spill over into India -- a reference to Islamabad's battle with Islamic militants in its northwest.

"We must be vigilant about the happenings on our western border, while at the same time, try to make peace with our neighbour," the Press Trust of India news agency quoted Antony as saying.

Jones is due to meet Antony later Friday.
