Kasab in his own words: I am Pakistani and a terrorist

Pakistan wanted proof and now it is there in the killer's own words and in his own hand. Ajmal Amir Kasab, the lone captured terrorist in Terrorist Ajmal Amir Kasab

Mumbai, has written a three-page letter to the Pakistani High Commission, stating that as a citizen he was entitled to seek legal help from his own country to fight his case in Indian courts. ( Watch )

The document not only finally settles the debate about the origins of Kasab and his fellow terrorists is a major embarrassment for Islamabad which has dithered about accepting that the Mumbai attack was launched from Pakistani soil.

Perhaps, what's worse for the detractors in Islamabad is a confession contained in the letter written in Urdu. "Mein sabse bara gunehgar hoon, kitne bekasoor logon ki jaan li hain, Khuda mujhe maaf karein (I am the biggest sinner, I have killed so many innocent people, may God forgive me),'' the terrorist wrote in a repentant tone.

"Sabse bara gunehgar to mein mere maa-baap ka hoon... unke dil ko thes pahunchaya hain (My biggest crime is against my parents... I have given them immense pain).''

Kasab has also requested the Pakistani high commission to at least bury Ismail Khan's body in Pakistan. It was Khan's last wish, the letter added. Khan was the terrorist who accompanied Kasab as they spread terror from CST to Girgaum Chowpatty."Uski aakhri khwaiash thi ke marne ke baad usko Pakistan mein dafnaya jaye (His last wish was that he be buried in Pakistan after his death),'' Kasab wrote.

"We have forwarded the letter to the Union home department which, in turn, will be sending it to the Pakistani high commission in New Delhi,'' joint commissioner of police (crime) Rakesh Maria said.

The letter contains details of his nine colleagues (and himself) Pakistan may now find difficult to ignore. Additional commissioner of police Deven Bharti said the letter had minute details of each of his nine colleagues killed on 26/11. It mentions not only their addresses but also names their handlers, including four important Lashkar-e-Taiba operatives: Hafeez Saeed, Zakir-ur-Rahman Lakhvi, Kahafa and Abu Hamza.

Kasab claims he had lost his head in the swirl of the jihad brainwashing by LeT and ISI operatives.

"Bahak gaya tha mein, Lashkar ke darindon ne mukhe phansa diya (I was misled, Lashkar's devils ensnared me),'' he said.

"Pure Pakistan ko badnaam kiya hai, Khuda mujhe maaf karein (I have tarnished Pakistan's image, may God forgive me).''

The letter also mentions that they were allowed a week's leave after they had completed their arms training some time in September. "They were told they could go anywhere they wanted to and Kasab, who left home two years before that, went to his village and met his old parents. He also took their blessings, saying he was going for jihad,'' Maria said.

The State Forensic Science Laboratory has sent a report of the two taxi blasts in Vile Parle and Wadi Bunder, confirming the use of RDX and petroleum oil in the two bombs. The composition of explosives was prima facie similar to those used in the 1993 serial blasts, Maria said.
