A 41-year-old man in the US has been executed for killing a convenience store clerk from India during a shooting spree in 2001 that he had said was retaliation for the September 11 terrorist attacks. 

Mark Stroman, a Texas death row inmate, shot at least three men he mistook for Arabs in the weeks after the attacks, killing two of them. He was convicted of killing Vasudev Patel, 49, during the attempted robbery of a convenience store near Dallas in October 2001.

He was also charged in the fatal shooting of Waqar Hasan, 46, a Muslim born in Pakistan. He was executed after the US Supreme Court yesterday rejected a last-minute appeal by one of his victims to save his life.
