Iran attacked by top UN human rights official for 20 executions
Iran has been criticised by the United Nations' top official for human rights for executing 20 people this week.
There were "serious doubts about the fairness of the trials, respect for due process and other rights of the accused" before the executions, said High Commissioner for Human Rights Zeid Ra'ad al-Hussein .
Iran's judiciary announced the executions on Tuesday, identifying those put to death as Kurdish Islamic extremists who were convicted of armed robbery, killing civilians and planning bomb attacks.
Mr Zeid said reports suggested most, if not all, of those executed were Sunnis from Iran's Kurdish minority.
Kurdish fighters have increasingly battled Iranian security forces in recent weeks in north-west Iran, leading to deaths on both sides.
