Kasab, the only one among 10 Pakistani terrorists caught after the 2008 Mumbai terror attack, was "quietly hanged" in Pune, about four years after he was caught during the killing spree, Geo News reported.
It quoted Indian reports as saying that he was transferred to Pune's Yerawada jail from Mumbai "in a covert manner as the Indian government did not want to draw too much hype to this high-profile hanging".
Most English-language Pakistani newspapers' websites used international news agencies to report Kasab's hanging. Some leaned on the Indian media for the story.
The Nation newspaper quoted a statement from Kasab as saying in January: "I was denied a fair trial."
Duniya TV added: "Kasab appealed in the Supreme Court claiming he did not receive a fair trial, but his petition was struck down in August."
The News also quoted Indian External Affairs Minister Salman Khurshid as saying that Kasab was a Pakistani and New Delhi acted according to law.
"If Pakistan or the family of Kasab came forward to claim his body, we will think what can be done. However, till now there has not been any such move by them," he was quoted as saying.
