The US has had no reliable information on the whereabouts of al-Qaeda leader Osama Bin Laden in years, US Defence Secretary Robert Gates has admitted.

Mr Gates told ABC News in remarks to be broadcast on Sunday: "Well, we don't know for a fact where Osama Bin Laden is. If we did, we'd go get him."

Last week a Taliban detainee in Pakistan said he had information that Bin Laden was in Afghanistan this year.

However, Mr Gates said he could not confirm that information.

Do they know more than they're telling us, ahead of an imminent arrest or escape?

British Airways has apologised after a photograph in a staff magazine showed a frequent flyer boarding pass in the name of Osama Bin Laden.

The image appeared on the front page of LHR News and was meant to promote the benefits of online check-in.

It showed a passenger holding up an iPhone displaying a boarding pass in the name Bin Laden/Osama, seat 07-C.

A BA spokesman apologised and said: "A mistake was made and we are working to find out how this occurred."
