WASHINGTON - There is no evidence that Mullah Omar has taken refuge in Karachi, the Pakistan Embassy here said Friday, refuting an American newspaper report that the Taliban leader had been shifted from Quetta to the port city with ISIs help. We have no evidence of his (Mullah Omars) presence in Pakistan, Nadeem Kiani, the embassy spokesmen, said while commenting on The Washington Times story that he had escaped to Karachi where he had inaugurated a new shura. If anybody in the US government knows of any Quetta shura or Karachi shura, why dont they share that intelligence with Pakistan so we can take care of the issue ourselves? We have not been made aware of any presence of Mullah Omar in the region, Kiani added. The spokesman drew attention to the fact that Pakistan has rendered great sacrifices in the ongoing fight against terrorists and pointed out that the ISI and Pakistani military have suffered a lot of losses fighting the terrorists. Our forces are fighting the Taliban in Waziristan and other areas, he stated. The terrorists are now killing and targeting innocent people in Pakistani cities. ISI is a very professional intelligence agency and these allegations are baseless. He also referred to the close cooperation between the US and Pakistan, saying they have 24-hour intelligence sharing. The Washington Times said that ISIs help to Mullah Omar reinforces suspicions that the Pakistani intelligence agency, is working against US interests in Afghanistan as the Obama administration prepares to send more US troops to fight there. Bruce Riedel, a CIA veteran and analyst on al-Qaeda and the Taliban, confirmed that Mullah Omar had been spotted in Karachi recently, according to the newspaper. Some sources claim the ISI decided to move him further from the battlefield to keep him safe from US drone attacks, Riedel, who headed the Obama administrations review of policy for Afghanistan and Pakistan last spring, was quoted as saying. There are huge madrassas in Karachi where Mullah Omar could easily be kept. Riedel also noted that there had been few suicide bombings in Karachi, which he attributed to the Taliban and al-Qaeda not wanting to foul their own nest. A US counterterrorism official said, There are indications of some kind of bleed-out of Taliban types from Quetta to Karachi, but no one should assume at this point that the entire Afghan Taliban leadership has packed up its bags and headed for another Pakistani city.
