"India has been a victim of Pakistan-aided terrorism, and intelligence reports still suggest that terrorists based in that country are planning attacks in India similar to last year's Mumbai carnage," Singh said in an interview to the 'Washington Post' ahead of his visit to the state.
He asserted that Pakistan has "nothing to fear" from India, and it was a "tragedy" that Pakistan has come to the point of using terror "as an instrument of state policy".
"Every day I receive intelligence reports saying that terrorists based in Pakistan are planning other similar acts,"
Singh said India wanted the US to use all its influence with Pakistan to ask it desist from that path.
When asked about actions being taken by Pakistan to bring to book those involved in the Mumbai terror attack, the Prime Minister said they have not done enough.
"As far as perpetrators of the Mumbai massacre are concerned, (Pakistan) has taken some steps but not enough," he said.
Singh also expressed concern about the rise of terrorism in Pakistan and said terrorists' increasing grip over several parts of the country was a threat to India's security as well.
