The attack on the US embassy and the NATO headquarters in Kabul were blamed on the Haqqani Network, which US Admiral Mike Mullen called "a veritable arm of Pakistan's Inter-Services Intelligence Agency." Pakistan reacted by recalling its finance minister who was on a visit to the U.N. Pakistan also tried to strengthen the relationship with China and Saudi Arabia to counter the U.S. The Chinese government advised Pakistan against any commitments that could jeopardize China's relationships with US and India. The United States reissued a call urging Pakistan to act against the Haqqani Network or else the US would be forced to take on the threat unilaterally. Islamic groups in Pakistan, issued a fatwa proclaiming Jihad against the US. This was followed by Pakistan threatening the US with retaliation, if the US went ahead with unilateral action against the Haqqani network.
