Amnesty International's latest global report on the death penalty, "Death Sentences and Executions: 2013," finds that a number of nations in the Middle East have fueled a spike in global figures with a spree of executions. Iran, Iraq and Saudi Arabia alone accounted for almost 80% of all reported executions carried out worldwide in 2013—excluding China, where official figures are secret. The upsurge in executions in Iran and Iraq accounts for a global jump of nearly 15% from 2012. Across the Middle East and North Africa, at least 638 people were executed in 2013—mostly by beheadings, hangings or firing squad. In Iran, Saudi Arabia and the United Arab Emirates, capital punishment was imposed for drug offenses. In Saudi Arabia, one man was executed for "adultery." Vaguely worded offenses, such as moharebeh ("enmity against God"), were used in Iran to repress the political activities of ethnic minorities such as the Kurds.
