Executions are often undertaken in an extremely public manner, with public hangings in Iran or live broadcasts of lethal injections in the US. According to UN human rights experts, executions in public serve no legitimate purpose and only increase the cruel, inhuman and degrading nature of this punishment.
“All executions violate the right to life. Those carried out publicly are a gross affront to human dignity which cannot be tolerated,” said Hassiba Hadj Sahraoui, Amnesty International’s Deputy Director for the Middle East and North Africa.
