New Delhi asked for a postponement of the Srinagar-Muzaffarabad bus service talks that were supposed to have been held in Islamabad on April 8-9 but the issue has now become politically sensitive given yesterday’s grenade attack on the PDP rally called to welcome the bus service. With Prime Minister A B Vajpayee’s proposed trip to the Valley on April 11, the PDP has raised the pitch. In fact, the postponement of the talks after ‘‘mutual consultations’’ between India and Pakistan was announced just the day before, too late for the PDP to call off its rally in Uri, the last bus stop before the Line of Control begins. State Finance minister Muzaffar Beig and Tourism Minister Ghulam Mir were injured in the attack that killed 11 people and in which PDP chief Mehbooba Mufti had a narrow escape. Over a hundred were injured. At the rally yesterday, an emotional Mehbooba had said that those behind the attack were against the opening of the road since they wanted to derail the peace process. Even the Hurriyat, which is now pushing for a poll boycott, wants the road opened and the bus service resumed—the first time since 1956.But sources here said that India’s request to postpone the discussions came as a relief to the Pakistani side, which has for some time now evaded the issue of what documentation passengers would carry. While Islamabad favours UN documents, Prime Minister Mir Zafarullah Khan has said ‘‘all modalities’’ would be considered. Friend Tarigami to take on Mehbooba in Anantnag
