A multiple murderer who went on the rampage after the 9/11 attacks, killing two people he thought were Arabs, has been executed in the US state of Texas.

Mark Stroman, 41, died by lethal injection despite last-minute representations by his lawyer at the US Supreme Court.

In his final weeks Stroman's plea for clemency was backed by Rais Bhuiyan, who was shot but survived. Mr Bhuiyan had said that killing Stroman was "not the solution".... ....Speaking to the BBC before Stroman's execution, Mr Bhuiyan, 37, said Stroman was guilty of "hate crime", but warned that his death would not achieve anything.

"His execution will not eradicate hate crimes from this world. We will just simply lose another human life," Mr Bhuiyan said.

...Stroman admitted the killings, saying he was motivated by anger at the 9/11 attacks and wanted to take revenge on Muslims - or people who resembled Muslims.

"I had some poor upbringing and I grabbed a hold of some ideas which was ignorance, you know, and hate is pure ignorance. I no longer want to be like hate, I want to be like me," he told the BBC.
