Pakistan national Mohammad Ajmal Kasab was the enduring image of the bloody assault, which traumatized India and raised fears of copycat attacks on foreign cities. Pictures of the young 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 hanged amid great secrecy, underscoring the political sensitivity of the Nov. 26, 2008, massacre, which still casts a pall over relations between nuclear-armed rivals Pakistan and India.
“All the police officers and personnel who lost their life in the battle against the terrorists have today been served justice,” Home Minister Sushil Kumar Shinde said after Kasab was hanged in a jail in Pune, southeast of Mumbai.
A senior commander of Pakistan's Lashkar-e-Taiba (LeT) militant group, which India blames for the assault on Mumbai, called Kasab a hero and said he would inspire more attacks.
“To die like Kasab is the dream of every fighter,” the commander told Reuters by telephone from an undisclosed location.
The Pakistan Taliban said they were shocked by the hanging.
“There is no doubt that it's very shocking news and a big loss that a Muslim has been hanged on Indian soil,” Taliban spokesman Ihsanullah Ihsan told Reuters.
Kasab was buried inside the prison where he was hanged, officials said. India said it would hand over the body to Pakistan if a request was made.
It was the first time a capital sentence had been carried out in India since 2004. There was relief on the streets of Mumbai as news of the execution swiftly spread.
“When I heard the news of Kasab's execution today, I remembered those horrifying moments of the attack,” said Vishnu Zende, who was working at Mumbai's train station on the day of the attack.
