The killing of Osama Bin Laden

The US tracked down the al-Qaeda leader to a city in northern Pakistan in May 2011. Special operations troops were sent to capture or kill Bin Laden in a top secret raid in the dead of night. The Americans did not tell their Pakistani allies about the raid beforehand. Gabriela Jones spoke to Nicholas Rasmussen who was in the White House situation room with President Barack Obama and US military chiefs as the raid took place.Photo: Osama Bin Laden's fortified compound on the outskirts of Abbottabad in north-west Pakistan.
