"I decapitated with my blessed right hand the head of the American Jew, Daniel Pearl, in the city of Karachi, Pakistan," Mohammed told a military panel, according to a Pentagon transcript released Thursday. "For those who would like to confirm, there are pictures of me on the Internet holding his head."

In 2002, an anti-terrorism court in Karachi sentenced Ahmed Omar Saeed Sheikh, a British-born militant, to death and gave three other men life in prison for involvement in Pearl's killing.

Rai Bashir a lawyer for Sheikh and the other three men said on Sunday that he will study the Pentagon documents on Mohammed's claim and file his confession as evidence to prove Sheikh's innocence.
