Arizona execution takes two hours
US death row inmate Joseph Wood has died after an execution in Arizona took nearly two hours to kill him.
Wood, a double murderer, was executed by lethal injection.
His lawyers filed an appeal for an emergency stay of execution, after he had been "gasping and snorting for more than an hour" in the death chamber.
Arizona Governor Jan Brewer says she has ordered a full review of the execution, although she said that Wood "died in a lawful manner".
Wood's lawyers argued the extended execution process violated his right to be executed in the absence of cruel and unusual punishment.
But Ms Brewer said: "By eyewitness and medical accounts he did not suffer. This is in stark comparison to the gruesome, vicious suffering that he inflicted on his two victims, and the lifetime of suffering he has caused their family."
