Bin Laden Running Out of Places to Hide: Washington - With the rapid collapse of the Taliban, the United States has intensified its pursuit of Osama bin Laden and his network, adding more commandos to the chase and aiming more air strikes at hideouts near the border with Pakistan, officials said on Sunday. Dozens of additional special operations troops have entered Afghanistan since Thursday, officials said, in the north as well as in a narrowing band of mountains along the southeast border with Pakistan, where intelligence reports suggest he is most likely to be.
