Israel has warned its citizens across the world that there are “concrete” indications they will be targeted by terrorists in the coming weeks.

The government’s Counter-Terrorism Bureau has warned Israelis and Jews to stay away from dozens of countries in the run-up to the High Holy Days, calling it “a favoured period” for organisations such as al-Qaeda to strike.

The Bureau banned Israelis from visiting Algeria, Djibouti, Mauritania, Libya, Sudan, Somalia and Tunisia.

Israelis were also advised to avoid Turkey, Azerbaijan, Indonesia, Ivory Coast, Malaysia and Nigeria.
