Israel on Monday advised its citizens to leave Turkey citing the potential for attacks after three Israelis were among four people killed in a March 19 suicide bombing in Istanbul.

"It has been decided to upgrade the existing travel warning vis-a-vis Turkey from a basic concrete threat to a high concrete threat, and to reiterate our recommendation to the public to avoid visiting the country and –- for Israelis currently in Turkey -– to leave as soon as possible," a government statement said.
