It's now known that nearly a million people died in the Rwandan genocide twenty years ago, but when Dateline sent reporter Helen Vatsikopoulos to cover the story in 1994, the country was in chaos... struggling with the divisions that led to so many deaths and injuries.
What was shocking too was the number of people forced out of the country into neighbouring Zaire, now the Democratic Republic of Congo.
She recalls what she saw there and she talks about dealing emotionally with the terrible scenes she witnessed.
Helen also won Dateline's first Walkley Award in 1992 for her story, Turkey or Iran? The Soviet Muslim Dilemma.
The collapse of the Soviet Union had left a strategic black hole in an area which historically had been contested by Russia, China, Iran and Turkey.
With the race on to fill the vacuum, Helen reported from Azerbaijan on the difficult choices facing the former Union’s muslim states.
