Officials in the US state of Oklahoma have reportedly postponed the second of two executions set for today after the first lethal injection was botched.
The Associated Press said the execution of Clayton Lockett was stopped after he apparently regained consciousness.
Lockett then suffered a heart attack and died around half an hour after officials halted the execution.
Now the execution of Charles Warner, which had been due two hours after Lockett's, will be stayed for a fortnight.
