Nearly a decade after the September 11 attacks, the founder and leader of al-Qaeda, Osama bin Laden, is dead.Calling it it "the most significant development" in the fight against al-Qaeda, President Barack Obama said tonight that bin Laden was killed in a firefight in Pakistan, which was the result of a "targeted assault" ordered by the President."This momentous achievement marks a victory for America, for people who seek peace around the world, and for all those who lost loved ones on September 11, 2001," said Mr. Obama.The President then remarked that "the fight against terror goes on."The fate of the organization's second in command, Ayman, al-Zawahiri, remains unknown."What remains to be seen is whether the death of the leader of Al Qaeda galvanizes his followers by turning him into a martyr, or whether it serves as a turning of the page in the war in Afghanistan and gives further impetus to the Obama administration to bring American troops home," writes Helene Cooper in the New York Times.
