Samaritan Passover 2015

Members of the Samaritan sect in Israel skewer sheep for the traditional Passover ceremony in West Bank city of Nablus (Khaleda Rahman, The Daily Mail)

• Passover is a commemoration of when the children of Israel were freed from slavery and led out of Egypt by Moses
  
• Some Jews practiced animal sacrifice for Passover in ancient times, but today it is only done by the Samaritans
  
• They were descended from the ancient Israelite tribes, but broke away from mainstream Judaism 2,800 years ago
  
• Because of a less than strict adherence to Judaism and part-pagan ancestry, they were despised by ordinary Jews

With lots of photos. On the last bullet point, it depends on what you mean by a "less than strict adherence to Judaism." I think the Samaritans would say that that they held a strict adherance to Samaritanism. But yes, until recently, there was considerable hostility between Samaritans and Jews. Past posts on the Samaritan Passover, which comes a little after the Jewish Passover, are here and here and links.
