Obama: Al-Qaida head bin Laden dead

WASHINGTON – Osama bin Laden, the glowering mastermind behind the Sept. 11, 2001, terror attacks that killed thousands of Americans, was slain in a firefight Sunday with U.S. forces in Pakistan, ending a manhunt that spanned a frustrating decade.

"Justice has been done," President Barack Obama said in a dramatic late-night announcement at the White House.

A jubilant crowd of thousands gathered outside the White House as word spread of bin Laden's death. Hundreds more sang and waved American flags at Ground Zero in New York — where the twin towers that once stood as symbols of American economic power were brought down by bin Laden's hijackers 10 years ago.
