CIA disbands unit set up to hunt for bin Laden

The CIA has disbanded a unit set up in the 1990s to oversee the spy agency's hunt for Osama bin Laden and transferred its duties to broader operations that track Islamist militant groups, a U.S. intelligence official said on Tuesday.
The bin Laden unit, codenamed Alec Station, became less valuable as a separate operation as counterterrorism operations eliminated top al Qaeda operatives and the movement's focus shifted more to regional networks of militants, said the official, who spoke on condition of anonymity.
