Ajmal Amir Kasab, the lone surviving terrorist of the Mumbai carnage, should be hanged at the Gateway of India to pay a 'real tribute' to the martyrs killed while saving lives during the attacks, daughter of a slain constable has demanded.

"It would be insulting to our martyrs if Ajmal is let off on humanitarian grounds without any punishment," Vaishali, daughter of Tukaram Ombale, who was killed during the terror siege, said in an interview to Shiv Sena mouthpiece 'Saamna' on Friday.
