President Barack Obama says the United States has conducted an operation that's killed Osama bin Laden, the mastermind behind the September 11, 2001, attacks.


Speaking from the White House in a late night address, Obama said a small team of Americans launched a targeted operation that he approved. He said no Americans or civilians were killed. Bin Laden's body was retrieved after a brief firefight.


"Tonight we can tell the families whose loved ones have been harmed by al-Qaeda: Justice has been done."


Numerous media outlets say the U.S. confirmed bin Laden's remains with DNA testing.


An American official says bin Laden was killed in a mansion about 40 miles outside the Pakistani capital.
