Jewish Tunisians who organize an annual pilgrimage to one of the world's oldest synagogues are planning a scaled-down event next month, citing concerns about security less than a year after a deadly shooting there shook their community.

Thousands regularly make the journey to Djerba — the North African island where many of Tunisia's remaining 1,500 Jews reside — to celebrate the Jewish holiday Lag B'Omer. But this year, the community has decided to limit them to the 26-century-old El-Ghriba synagogue instead of the island-wide events traditionally held.
