Xenocide is 'killing the other', for example when a person targets Jews in a synagogue, or Gays in a gay bar.

It comes from the Greek word 'xeno' which means foreigner, and the Latin ending '-cide' to mean to kill, as in suicide.

Jus as the word xenophobia means the fear of outsiders, xenocide is the killing of people deemed to be outsiders.
