Pakistan on Wednesday claimed it has not received any letter from Mohd Ajmal Amir Kasab, the lone terrorist arrested in Mumbai attacks, seeking legal aid and persisted with its denial mode on his Pakistani nationality, saying it needed "incontrovertible" evidence about it.
"Please don't give too much importance to newspaper reports. No letter has been delivered to me or to the (Pak) High Commission," Pakistan High Commissioner to India Shahid Malik told Karan Thapar in India Tonight programme of CNBC TV-18.
The High Commissioner was asked about the accused's father accepting after seeing photographs in newspapers and television that the terrorist is his son.
"Not when it comes to dealing with such individuals... We need something which is incontrovertible which cannot be challenged in a court of law," he said.
Malik said Pakistan was not contemplating giving access to Zaki-ur-Rahman Lakhvi, the alleged mastermind of the Mumbai attacks, to FBI for investigation.
"At the moment we are not contemplating it...Please allow us to carry forward the process of investigation and see whether there is any merit in involving others or not," he said.
