Amnesty International has slammed the world's most powerful G20 countries for their sometimes "horrific" human rights record.
Australia, although a G20 member, is spared some of the harshest criticism.
But the list of human rights abuses in the G20 countries collectively is "depressingly long", Amnesty International says.
The human rights group cites arbitrary detention without charge or trial in 14 of the G20 nations, unfair trials in nine, and torture or grave ill-treatment during interrogation in 15.
Five of the G20 countries - China, Saudi Arabia, the USA, Indonesia and Japan - are also singled out for carrying out 78 per cent of all state executions across the world.
