Sir: Pakistani is deeply concerned about the prevailing situation in the country and there seems to be no let-up in sight. Both the camps of marchers are least worried about the collateral damage. They sing, dance and celebrate their adventurism by waving victory signs. The residents of Islamabad are under great stress. A new dimension is added to the crisis daily to complicate the situation. A retired official of the Election Commission of Pakistan made revelations of his own to implicate the superior judiciary as well as the Chief Election Commissioner in the rigging charges. His disclosures at this juncture are dubious. There is no denying the fact that the government is exercising utmost restraint to avoid any unpleasant situation but the marchers take it as some sort of achievement of their own. Mediation efforts do not seem to be working. Perhaps they want turmoil and instability to achieve their object.M Younas QamarIslamabad
