Multiple news sources report that the U.S. has killed Osama bin Laden and has the terrorist's body. President Obama will address the nation on an undisclosed matter of national security shortly, and is expected to confirm this development. CNN reports that bin Laden was killed in a mansion outside Islamabad with other family members. Crowds gathered outside the White House chanting "USA!" and "hey, hey, goodbye" starting around 10:30 pm Sunday night.
