Meeting in Pakistan Reveals Tensions Over Afghan Peace Talks ISLAMABAD, Pakistan - Tensions between Pakistan and Afghanistan over mooted Taliban peace talks spilled into the open Friday, when Pakistan's foreign minister described as "preposterous" Afghan demands that her country deliver the insurgent leadership to the negotiating table. "If that is the expectation, there is no reality check," said Hina Rabbani Khar, when asked if Pakistan could produce the Taliban leader, Mullah Muhammad Omar. It is not only unrealistic but preposterous. Ms. Khar was speaking at the conclusion of a two-day trilateral summit between the leaders of Iran, Afghanistan and Pakistan in Islamabad that ostensibly focused on regional cooperation, but was overshadowed by a tentative American-driven initiative to start peace talks with the Afghan Taliban. Her comments were important because the Taliban leadership - and many of its fighters - are believed to be either hiding in Pakistan or using Pakistan's tribal belt as a base to attack Western and Afghan forces inside Pakistan. Pakistan's civilian and military leaders have repeatedly stressed their support for an "Afghan-led" peace process, but insist they have little direct control over the Taliban fighters on their soil - a position that infuriates the Afghan government and President Karzai, which accuse Pakistan of orchestrating the insurgency. During a bilateral meeting on Thursday, President Karzai asked Pakistan's leaders to "use their influence" to help bring the Taliban to the talks table, said the interior minister, Rehman Malik, who was present. Other Pakistani officials downplayed reports that President Karzai angrily upbraided the Pakistanis during the meeting. But on Friday President Karzai told a press conference of "impediments" in his relationship with Islamabad that needed to be removed "sooner rather than later." The terse comments exposed President Karzai's quandary. He is wary of American attempts to broker peace, fearing it will leave him politically isolated, yet harbors a deep suspicion of Pakistan that stretches back over a decade. Pakistani leaders, for their part, say Mr. Karzai and his American allies need to provide "clarity" on what shape any Taliban will take, before they can commit. "We will support any Afghan-owned and Afghan-led process," said Ms. Khar, but she added that Pakistan needed clarity about that process and "what degree of ownership" Afghanistan had over it. The Obama administration wants to anchor the peace process in the Gulf state of Qatar, where the Taliban is due to open a liaison office. As a goodwill gesture to the insurgent leadership, the United States is considering releasing five Taliban prisoners from the detention facility at Guantanamo Bay. But Mr. Karzai has been less enthusiastic about Qatar, and in comments to Pakistani reporters on Friday, he talked instead about a different talks process that would be based in Saudi Arabia or Turkey. During a press conference at the end of the summit, President Mahmoud Ahmedinejad of Iran brushed off questions about his country's controversial nuclear program. "The nuclear bomb will not bring superiority to any nation," he said, before launching an attack against countries with "hegemonic designs" - a clear reference to the United States. But speculation that Israel could attack Iranian nuclear sites loomed unspoken over the talks, given the likely repercussions for Iran's eastern neighbors. Pakistan's interior minister, Mr. Malik, called on the international community to resolve the crisis peacefully. "Let us not open another door of conflict," he said. The trilateral summit took place against a backdrop of continuing violence inside Pakistan. On Thursday two American drones killed 21 people in North Waziristan, in the northwestern tribal belt. On Friday, as the three leaders were meeting in Islamabad, an apparent suicide attack at a bazaar in Parachinar, a tribal town with a history of sectarian violence, killed at least 13 people and wounded 30 more, official said. Security forces opened fire on protesting villagers after the bombing, wounding seven more, and an indefinite curfew has been imposed on the area.
