A simple ploy using a mobile phone may have helped Taliban leader Osama bin Laden to escape US forces in Afghanistan and flee to Pakistan.
A report in The Washington Post suggests that bin Laden believed US spy technology had locked onto the signal from his mobile phone.
He gave his handset to a trusted Moroccan bodyguard, who moved away from bin Laden and his entourage as they fled in the aftermath of the battle of Tora Bora in late 2001.
The bodyguard continued to use the phone in an effort to divert the US forces and to allow their most wanted man to escape.
The bodyguard was later captured with the phone in his possession, officials told the newspaper.
