The death of the reviled US enemy, after a huge manhunt, sparked an explosion of joy across the United States, especially in New York and Washington, the targets of the worst-ever attack against the US mainland in 2001.

Bin Laden's demise also marked the biggest triumph yet in the 10-year war against terrorism, which has led the United States into two bloody wars, transformed its foreign policy and reshaped many aspects of American life.
