Mr Qasab retracted a confession he made earlier this year
The man alleged to be the sole surviving gunman in the 2008 Mumbai (Bombay) attacks, Mohammad Qasab, has said four of the gunmen were Indians.
Mr Qasab told a court that three of the four gunmen who stormed the Taj Mahal hotel were from Indian-administered Kashmir, Gujarat and Mumbai.
He did not reveal details about the identity of the fourth hotel attacker but claimed that he too was Indian.
The attacks led India to suspend peace talks with Pakistan.
India maintains that all the gunmen involved in the Mumbai attacks were from Pakistan.
Pakistan denied any responsibility in the immediate aftermath of the attacks, but later admitted they had been partly planned from its soil.
In December 2009, Mr Qasab retracted a confession made earlier in the year that he took part in the attacks.
Mr Qasab, who is Pakistani, said he had been forced by police to confess after being repeatedly beaten up.
The bodies of the nine gunmen killed during the attacks remain unclaimed.
