Islamabad, Pakistan (CNN) -- Tensions among Pakistan, Afghanistan and the United States jumped a notch Monday, with Pakistan's prime minister warning there would be "no more business as usual" with Washington after NATO aircraft killed two dozen Pakistan troops. Pakistani Prime Minister Yousuf Raza Gilani told CNN in an exclusive interview that Pakistan is re-evaluating its relationship with the United States in light of the airstrike, which NATO called a "tragic unintended" event. He said the South Asian nation wants to maintain its relationship with the United States so long as there is mutual respect and respect for Pakistani sovereignty.
