The UN High Commissioner for Human Rights Zeid Ra'ad Al Hussein on Aug. 5 criticized Iran for the mass execution of 20 people this week, calling the action "deplorable." The prisoners were all convicted of terrorism-related offenses, but the commissioner expressed doubt as to the fairness of those trials, deriding Iran as having expressed a "disdain" toward due process. In his statement, the commissioner called the executions a "grave injustice" and pointed out that many of those killed were Kurds or part of the Sunni religious minority.

For a third year running, Amnesty International's annual report on the death penalty notes an alarming surge in the number of executions worldwide—now reaching the highest total since 1989. At least 1,634 people were executed in 2015, a rise of more than 50% over the previous year. Iran, Pakistan and Saudi Arabia were leading the field, responsible for 89% of the executions. Iran executed at least 977 in 2015—the vast majority for drug-related crimes—compared with 743 in 2014. Those put to death included at least four who were under 18 at the time of the crime—which Amnesty called a violation of international law. Pakistan continued what Amnesty called as a "state-sanctioned killing spree" that began when a moratorium on civilian executions was lifted in December 2014. Pakistan sent at least 326 to the gallows last year, the highest annual total Amnesty has recorded for that country. Executions in Saudi Arabia rose by 76%, with at least 158 people put to death, Amnesty said. Most were beheaded, with the bodies often displayed in public.
