Are his pursuers closing in on Osama bin Laden in Pakistan?

Last week, NPR's Mary Louise Kelly wrote that the al-Qaida leader might be running out of space.

Today, CIA Director Leon Panetta had this to say to reporters:

"I guess one of our hopes is that as Pakistani military moves in, combined with our operations, we may have a better chance to get at him."

The Associated Press adds that Panetta:

Said the Pakistani offensive in the Swat Valley is making very good progress compared to Pakistan's past efforts to crack down on extremists. The Pakistan military says it has killed more than 1,300 militants during the offensive and reclaimed most of the region.
