Pakistan national Mohammad Ajmal Kasab was the enduring image of the bloody assault, which traumatised India and raised fears of copycat attacks on foreign cities. Pictures of the boyish gunman wearing a black T-shirt and toting an AK-47 rifle as he strode through Mumbai's train station were published around the world.
Kasab was executed on the morning of November 21.
Family members of the victims welcomed the government's decision to hang Kasab, but cautioned that the wounds of 2008 attacks would never be fully healed.

India secretly executed the lone surviving gunman on Nov. 21, from the 2008 Mumbai attack, four years after Pakistani gunmen blazed through India's financial capital, killing 166 people and shattering relations between the nuclear-armed neighbors.
