The German town of Nuremberg is marking the 65th anniversary of the trials held there against Nazi leaders at the end of the second world war.
Representatives from all the former allied countries attended an official ceremony opening an exhibition in the historic courtroom.
The legal proceedings became the model for international trials of the future.
The exhibition is largely media based with video footage from the original trials. It also gives background on the 21 high-ranking Nazis who were in the dock.
Back in 1945 the Nuremberg trials broke new ground in holding government leaders individually responsible for their aggression. They also established new offences such as crimes against humanity.
