What you need to know:

  • Some rights groups believe around 20,000 so-called dissidents were slaughtered by Mugabe's ruthless Fifth Brigade, which was trained by North Korean forces.
  • The operation was known as "Gukurahundi" -- Shona for "the rain that blows away the chaff before the spring rain".
  • In 2000, gangs of men armed with axes and machetes started invading white-owned farms across Zimbabwe.
