Pakistan PM: NATO blockade could last weeks

Pakistan\'s blockade of the US supply line into Afghanistan, ordered in retaliation for a border strike, is likely to stay in place for weeks, Prime Minister Yousuf Raza Gilani has told the BBC. Pakistan\'s fragile alliance with the United States crashed to new lows after November 26 when NATO air strikes killed 24 Pakistani soldiers in what the Pakistan military called a deliberate attack. Gilani said in an interview with the BBC aired Sunday that the ban, already in its third week in the longest closure of the 10-year war, would not be lifted until new \"rules of engagement\" were agreed with Washington. Asked whether that would be a matter of days or weeks, he replied: \"weeks\". Gilani said there was still a \"credibility gap\" with the United States. \"We are working together and still we don\'t trust each other. I think we have to improve our relationship.\" \"We want to set new rules of engagement and cooperation with United States. We have a resolve to fight against terrorism and therefore we want to set new rules of engagement,\" he added. Gilani stood by Pakistan\'s declaration that the border incident was a pre-planned attack, an allegation Washington rejects. \"Apparently yes and still there is an internal inquiry being conducted and we are waiting for the results,\" he said, adding that the motive for such a deliberate attack remained \"a big question mark\". US President Barack Obama telephoned President Asif Ali Zardari to offer his condolences over the strike, but Washington has stopped short of apologising pending the outcome of a military probe due out on December 23. Although Pakistani and US officials dispute the precise sequence of events, Pakistan closed its two crossings to US and NATO supplies and ordered American personnel to leave an air base reportedly used by CIA drones. Pakistani-US relations, which have yet to recover from a secret American raid that killed Osama bin Laden on May 2, are considered at their lowest ebb. In the interview, Gilani also said that Zardari has not suffered a stroke nor offered to resign despite rumours triggered when he flew to the United Arab Emirates for medical treatment a week ago. Zardari fell ill in the midst of a major scandal over alleged attempts by a close aide to seek US help to limit the power of Pakistan\'s military. \"There was no stroke,\" Gilani said in the interview with BBC World News. \"He is improving and he is now out of ICU and he has been shifted to his room and I think he will take rest for about two weeks,\" he said.
