Worried over the rise in terror incidents in Pakistan and Afghanistan, Prime Minister Manmohan Singh on Sunday asked the global community to extend sustained cooperation for dealing with the menace for ensuring stability in the region.

"We are very worried about the rise of terrorism in our neighbourhood, particularly what is going on in Afghanistan and in Pakistan. We have a vital stake in peace, progress and stability of these countries and other countries of South Asia," Singh said while inaugurating the India Economic Summit here.

He said India has been a victim of terrorism, "unfortunately coming from across our border for the last 25 years" but the world discoverd it as a global problem only after 9/11 (attack on the US).

"I sincerely hope that among the processes, which require sustained international cooperation, dealing with terrorism figures very high on the priorities of all civilized countries of the world," he said.

India is concerned over a sharp rise in deadly terrorist attacks in various parts of Pakistan and Afghanistan in recent past.

The American agency FBI has recently uncovered a plot by nabbing David Coleman Headley who was hired by the Pakistan-based militant outfit Lashkar-e-Taiba to carry out attacks in India.
