The number of executions is in decline worldwide, comparing last year's figures to the year before. However, the number of death penalties handed down has increased in 2016, as stated in a recent report by Amnesty International (AI). Most executions by far still occur in China. AI estimates that thousands of people were executed in there. Chinese authorities do not publish official figures. Iran has the second deadliest justice system in place, followed by Saudi Arabia, Iraq and Pakistan. The United States executed 20 people last year. Amnesty International is campaigning for a worldwide abolition of the death sentence, especially for minors.
