Did Pakistan know Osama Bin Laden's whereabouts?

The Pakistani authorities are under growing pressure to explain how the al-Qaeda leader, Osama Bin Laden, could have lived just minutes away from a military facility without being discovered.

There are now calls for the White House to release proof that Bin Laden was killed in the operation on Sunday night.

The BBC's Orla Guerin has been looking around the compound in Abbottabad and sent this report.
