Prime Minister Syed Yousuf Raza Gilani said on Saturday that due to terrorism the nation was experiencing severe psychological depression. He was speaking at the inaugural session of a seminar on psychological problems organized by National University of Science and Technology. Gilani said the scourge of terrorism was present in its worst form in the country and several great personalities had fallen prey to it, including former PPP Chairman Benazir Bhutto. He said just like the way the nation had earlier stood up to the challenge of 2005 earthquake, it should now face the new challenge of terrorism with the same spirit.
