And turning now to the United States.
A botched execution in the state of Oklahoma has reignited the debate over the death penalty.
38-year-old Clayton Lockett was scheduled to be put to death by lethal injection on Tuesday, but doctors stopped the execution when he began convulsing and writhing in pain.
He then died of a massive heart attack about 40 minutes after the procedure.
State officials had been testing a new cocktail of chemicals in its lethal injections.
Human rights groups have condemned the incident as torture and called for a nationwide ban on capital punishment.
The Governor of Oklahoma Mary Fallin has ordered an independent review into the state's execution protocols.
She also said that executions for other death row inmates have been delayed pending the results of the investigation.
