Rwanda genocide memorial: How life has changed

Commemorations have been taking place across Rwanda to mark 20 years since the 1994 genocide.

In just three months, around 800,000 minority Tutsis were killed by the majority Hutu population.

It left a country in total ruin, faced with the huge task of bringing the Hutu killers to justice.

George Alagiah, who reported from Rwanda at the time, has returned to the country to see how it has dealt with the legacy of the genocide.
