ISLAMABAD - Pakistan on Sunday rejected the reported remarks of the US Director of National Intelligence James Clapper that Islamabad has stopped demanding end to CIA drone operations in FATA. There is no change in Pakistans stance on drone attacks. It is very clear that drone attacks are against the sovereignty of Pakistan, Foreign Office spokesperson Tehmina Janjua said. The spokesperson said that will never retreat from its principled stand on drone attacks and that the attacks are unacceptable for Pakistan, she said in response to the reported remarks of James Clapper. Meanwhile, commenting on Clappers statement, Director General ISPR, Major General Ather Abbas rejected the report as 'incorrect. This is absolutely an incorrect statement. Pakistan continues with its principled stance that CIAs covert drone strikes are counterproductive to fight against terrorism and against the countrys territorial sovereignty, the ISPR DG told TheNation. Military chief spokesperson, however, conceded that CIA and ISI are cooperating to fight common enemy Al-Qaeda and its affiliates. The relations between the US and Pakistan had gone to lowest since US unilateral May 2 raid on Abbottabad and after the recent allegations by Chairman of the Joint Chiefs Adm. Mike Mullen. Despite that Washington and Islamabad had maintained their diplomatic communications stable. The allegations of the US top military commander had led to a strong reaction in Pakistan from political and military leadership. Realizing gravity of the situation, the government last week had convened All Parties Conference (APC) that sent a very strong message to the United States cautioning grave consequences in case of any US misadventure. The APC also resolved that resolution it had adopted would be incorporated into the previous resolutions adopted by countrys sovereign parliament that also included ending of CIA operated drones hits. In a related development, US Special Representative Marc Grossman who is due to visit Pakistan shortly has underlined the need urging Pakistan, Afghanistan and US to work together against terrorism. In an interview, Grossman said the number of Pakistani civilians, who have been killed in terrorist attacks, is just enormous, as 19,000 of them have died since 2003. He said, Extremism and terrorism is a threat to Pakistan, and its a threat to Afghanistan, and its a threat to the United States. We ought to, all three of our countries, be able to work together to try to deal with this problem. He said that one of the things that were happening between Pakistan and the United States was that both were trying to have a conversation about how to get interests shared and then act on them together. What we continue to talk about is the need for engagement between the United States and Pakistan. And if I might add, also the need for engagement between Pakistan and Afghanistan.
