US Secretary of State Hillary Clinton has said there is no evidence senior people in Pakistan knew that Osama Bin Laden lived so close to Islamabad, the BBC reports. But she said that the US and Pakistan needed to do more to battle Islamist militancy and that bilateral relations had reached a turning point. Clinton said any peace deal in Afghanistan would not succeed unless Pakistan was part of the process. She expressed Washington’s “strong commitment” to relations with Pakistan. She was speaking after meeting Pakistani leaders on a seven-hour previously unannounced trip aimed at repairing ties badly damaged by the 2 May US raid that killed al-Qaeda chief Osama Bin Laden.
