Dead, captured and wanted

As the one-year anniversary of Osama bin Laden's death approaches, CNN has updated this list, originally published in September 2011, taking a look at some of the dead, captured and the remaining most wanted terrorists from the last 10 years.

While progress has been made, there are still terrorists being saught by the U.S. government. CNN spoke with a number of intelligence agencies to come up with this list of "dirty dozens." Here are the 12 most significant terrorists who are now dead, have been captured and those who are still being hunted. The lists are obviously subjective–there are many more candidates–but these are some of the top combatants in the war on terror.
