This week marks 15 years since the beginning of the Rwandan genocide. There was a candlelit vigil at the start of a week of national mourning to mark 15 years since the genocide which killed 800,000 people. You can read more on BBC News.
I visited Rwanda in August while I spent time in East Africa, and it impacted me strongly. You can read more about my experiences on that trip by going to my blog archives for Aug 2008.
