In Iran the authorities officially announced 289 executions, but hundreds more were carried out which were not officially acknowledged, Amnesty report said.
Execution methods employed around the world included beheading, hanging, lethal injection and shooting.
Iran is among the countries highlighted by Amnesty International as having used the death penalty “as a tool to suppress political dissent”.
