A U.S. man who went on a shooting spree for what he said was retaliation for the 2001 terrorist attacks has been put to death, after courts rejected a last-minute bid by a survivor to stop the execution.

Mark Stroman was lethally injected Wednesday night in the southern state of Texas after judges rejected appeals by the only remaining survivor of the attack.

Stroman was convicted of killing a 49-year-old Indian gas station clerk in October 2001. He was also charged with the murder of a 46-year-old Pakistani man in a separate attack.

The self-described white supremacist said he was targeting people he thought to be of Arab descent.

The surviving victim, Rais Bhuiyan, was blinded in one eye when Stroman shot him with a face with a shotgun. Bhuiyan, from Bangladesh, had argued against the death sentence, saying his Muslim faith calls for forgiveness.
