Rwanda genocide: Your questions

Rwanda is beginning a week of official mourning to mark the 20th anniversary of the country's genocide on Monday.

Between April and June 1994, some 800,000 ethnic Tutsis and moderate Hutus were brutally slaughtered in Rwanda.

The question many people are asking is: What led to such horrific events?

And How has Rwanda dealt with the aftermath, 20 years on?

BBC Africa's Kassim Kayira, who is from Rwanda, will answer your questions on Monday 7 April between 1200 GMT and 1300.
