At least five people were killed in a shooting attack at a Jewish synagogue in Tunisia yesterday. It happened at the Ghriba synagogue, a holy site in the Jewish Djerba pilgrimage, which brings thousands of Jews to Tunisia every year, mostly from France and Israel. The shooter was working as a guard at a nearby naval installation, but his motive remains unclear. To discuss this attack, and the history of this pilgrimage, The World’s host Marco Werman speaks to Daniel Lee, who is a historian of the Jews of France and North Africa at Queen Mary University of London.
