President Obama called a late night news conference to announce that Osama bin Laden is dead. He was shot in a firefight in Pakistan:

Osama bin Laden, the Saudi extremist whose al-Qaida terrorist organization killed more than 3,000 people in coordinated attacks on the U.S. on Sept. 11, 2001, is dead following a military operation in Pakistan and the U.S. has recovered his body, U.S. President Barack Obama announced Sunday night.

"Justice has been done," the president declared as crowds formed outside the White House to celebrate, singing "The Star-Spangled Banner" and "We Are the Champions," NBC News reported.

Obama said bin Laden, whom he called a terrorist "responsible for the murder of thousands of American men, women and children," was killed in Pakistan earlier in the day after a firefight in a military operation that was based on U.S. intelligence.
