Security has been tightened in Islamabad after the blasts in I-8 markaz and Bara Kahu Charsadda in which one guard died on the spot and several persons were injured. Security outside important police offices has been beefed up and personnel armed with sophisticated weapons have been deputed outside the police stations. Extra deployment of police personnel has been ensured at important locations of the city including chowks and signals. The war on terror has hit the capital city once again and now the higher authorities should make a plan to counter terrorism and a healthy environment for the citizens of Islamabad. I strongly believe that the locals should also cooperate with the police force so that their job becomes easier. KHURRAM SALEEM, Islamabad, June 14.
