The Prime Minister’s Office issued a travel warning Thursday advising Israelis to avoid Tunisia.

The warning, released the PMO’s Counter Terrorism Bureau, followed an updated situation evaluation and stressed credible threats of terror attacks against Jews and Israelis.

The bureau emphasized threats to people congregating in the city of Djerba on and around the upcoming Lag B’omer holiday on Thursday and Friday next week.

Djerba, noted for it’s 2.500 year-old Jewish community, was the site of a synagogue bombing in April 2002 that killed 21 and wounded 30 more.

The advisory was given a threat assessment level of three out of four, with a “specific-high” rating.
