Prime Minister Yousuf Raza Gilani said Thursday US drone attacks on Pakistani territory were "counterproductive" and called for a new approach by the US administration. Gilani explained that each drone attack undermined Pakistan's policy of trying to build relations with tribes in restive areas and separate them from militants. "When there is a drone attack that unites them again, the tribes and the militants," he told delegates here during a discussion about Pakistan and Afghanistan. "This thing is counterproductive for Pakistan and the Pakistan military," he said. He added: "Army action is not the only solution. We have to have a new strategy because in the US and in Pakistan, the people have voted for a change," he said. "The change should be visible."
