Washington, Nov 16 - Ajmal Amir Kasab, the sole surviving terrorist of the group of ten sent by the Pakistan based terror group Lashkar-e-Taiba to attack Mumbai, says his father essentially sold him into the group.

Kasab, who was part of the pair that killed 50 and wounded more than 100 at Chhatrapati Shivaji Terminus, the city's main railway station, makes the suggestion in tapes included in a new documentary, 'Terror in Mumbai' airing on HBO Thursday.

Snatches of cellphone conversations - many never heard before - between the gunmen and their controllers in Pakistan, as well as video footage of the police with Kasab were aired Sunday in a preview of the documentary by narrator Fareed Zakaria in his GPS programme on CNN.

One of the tapes of Kasab's interrogation points to how he got involved with the LeT terror group:

Kasab: He said, 'These people make loads of money and so will you. (Inaudible) We'll have money, we won't be poor any more. Your brothers and sisters can get married. Look at these guys living the good life. You can be like them,' he said.

Unidentified Male: Your dad said this?

Kasab: Yes. So, I said, 'Fine, whatever.'

Unidentified Male: What does he do for a living?

Kasab: He used to sell yogurt and potato snacks in the street.

Unidentified Male: How much did they give you? Did they put it in your account?

Kasab: There is no account. They gave it to my dad.

Unidentified Male: How much did they give him?

Kasab: I don't know. Maybe (ph) a few hundred thousand.

In another tape, Kasab recalls how the terrorist group was trained.

Police: How long were you in training?

Kasab: Three months. There were 24 or 25 in our class.
