Taliban and Pakistan Argue Over Fate of Islamist Detainee KABUL, Afghanistan - The Taliban on Wednesday publicly disputed claims by the Pakistani government that it had released a senior militant detainee, drawing a firm rebuttal from Islamabad and plunging efforts to start peace talks in Afghanistan into fresh confusion. The Taliban said in a written statement that Mullah Abdul Ghani Baradar, a founder of the Islamist movement, was "spending days and nights locked up behind bars in worrisome health conditions, which are deteriorating by the day." - The statement contradicts a Pakistani claim, made on Sept. 21, that Pakistani security forces had released Mr. Baradar in a bid to boost the faltering peace effort. Mr. Baradar was detained in the port city of Karachi in 2010 and his fate has become closely tied to efforts to kick-start negotiations. Last week Pakistani news media outlets reported that since his putative release, Mr. Baradar has been staying in guesthouses in the northwest of the country, under the watch of Pakistan's security services. It is unclear whether he can move of his own free will - or whether, as hoped, he has engaged other Taliban leaders in the talks process. On Wednesday, the Taliban said they was publicly addressing Mr. Baradar's position in response to news media speculation about his new role. "Some media outlets have gone as far as claiming that he is busy in political activities," they said. But Pakistan's foreign ministry insisted it had delivered on its promises to release the commander, describing him on Wednesday as one of several Taliban detainees freed to facilitate the reconciliation process. "Mullah Baradar has been similarly freed," said Aizaz Ahmad Chaudhry, the foreign ministry spokesman, in a text message. As far as we are concerned, he is free to meet and contact anyone to advance the cause of reconciliation. As often in the smoke and mirrors game of efforts to draw the Taliban into talks, it was difficult to know where the truth lies. The Taliban claim, if true, would renew concerns about Pakistan's commitment to peace talks. Just as likely, however, the statement was part of the complex and often opaque maneuvering involving insurgents, Afghan government officials, Pakistani spies and Mr. Baradar himself, as all sides balance the merits of talking versus fighting at a time when American combat forces are readying to leave Afghanistan next year. During a visit to Pakistan in the summer, President Hamid Karzai of Afghanistan personally pressed for Mr. Baradar to be released. When the announcement came in September that Mr. Baradar was finally set free, it was immediately hailed in Kabul and Washington as a sign that Pakistan, under new Prime Minister Nawaz Sharif, was sincere about moving forward peace talks and improving relations with Afghanistan. The Taliban, though, did not confirm Mr. Baradar's release at the time. Their silence reinforced doubts about what influence Mr. Baradar, a former deputy to the movement's leader, Mullah Muhammad Omar, would have within the insurgency after a long stint in prison. On Wednesday, the group added: "We earnestly ask the Pakistani government and officials to give clarification, and, just as they have announced, he should be released." The Taliban, who call themselves the Islamic Emirate of Afghanistan, added that "the Islamic Emirate and his family believe it to be his legitimate right to be freed under humanitarian and Islamic sympathy from his wrongful imprisonment due to his deteriorating health condition." Aimal Faizi, a spokesman for Mr. Karzai, said in an interview last week that there had been no contact between Mr. Baradar and the Afghan government. In a parallel but separate process, the Pakistani government is also considering peace talks with the Pakistani Taliban, although the prospects for success seem even more remote. On Wednesday the leader of the Pakistani Taliban, Hakimullah Mehsud, appeared in a BBC television interview, saying he was ready to enter negotiations. But Mr. Mehsud, who has a $5 million bounty from the United States on his head, also expressed skepticism that talks could go anywhere, and issued a list of demands that would be difficult for Islamabad to deliver, such as a complete cessation of American drone strikes in the Pakistani tribal belt. A lively debate in Pakistan about the merits of talking to the Taliban has been influenced by three major bombings in the northwestern city of Peshawar in recent weeks that killed at least 140 people, as well as an ambush on a military convoy in which a two-star general was killed. The BBC report on Mr. Mehsud also aired video of Taliban fighters playing on the edge of a small river, tossing each other into the water, in what may have been attempt by the insurgent movement to portray a lighter image of itself.
