Bin Laden "may have lived in Pakistan for over 7 years"

Reuters reports:

Osama bin Laden may have lived in Pakistan for over seven years before being shot dead by U.S. forces, senior Pakistani security officials said on Saturday, a disclosure that could further anger key ally Washington over the presence of enemy number one in the country.

One of bin Laden's widows told Pakistani investigators that he stayed in a village for nearly two and a half years before moving to the nearby garrison town of Abbottabad, where he was killed on Monday.
