Osama bin Laden, the founder of al-Qaeda, was killed during a raid by United States special operations forces on a walled compound in Abbottabad, a garrison town about 120 kilometres north of Islamabad.

President Barack Obama announced the operation in a late-night televised address, saying no American personnel were lost. The compound had been under surveillance for months after intelligence agencies tracked a courier to the property.

The operation, conducted without prior notice to Pakistani authorities, caused a serious rupture in relations between Washington and Islamabad that took years to repair.
