Pakistan's president denies harboring bin Laden

Pakistan's leader denied suggestions that his country's security forces sheltered Osama bin Laden as Britain demanded Tuesday that Islamabad answer for how the al-Qaida chief lived undetected for six years in a large house in a garrison town close to the capital. But in a nod to the complexities of dealing with a nuclear-armed, unstable country that is crucial to success in the war in neighboring Afghanistan, British Prime Minister David Cameron said having "a massive row" with Islamabad over the issue would not be in Britain's interest.
