NEW DELHI: Indian Prime Minister on Monday said that cross-border terrorism remains the most pervasive threat to India.

“There is need for utmost vigilance. There is credible information that terrorists in Pakistan will carry out fresh attacks in India, says Prime Minister Manmohan Singh.

Noting that there were signs of revival of over-ground militant activities, he said attempts were being made to link isolated and unconnected incidents to create an impression of a groundswell of anti-India feeling.

"All this shows that efforts to disturb the current status quo have not been given up,” Singh said.

Earlier, Indian union home minister P Chidambaram said that the gravity of the terror threat remains undiminished and the country cannot lower its guard.
