The Israeli authorities recommended the citizens of the Jewish state to refrain from trips to Turkey and countries bordering with Iran, the statement issued Monday by the Israeli government press office of the counterterrorism bureau of the National Security Council reads.

“For several weeks now, and even more so since Iran blamed Israel for the death of the Revolutionary Guards officer last week, there has been growing concern in the defense establishment about Iranian attempts to harm Israeli targets around the world,” a statement from the National Security Council said.

The National Security Council said it was “sharpening” the travel warning to Turkey, stressing that the country and other nations bordering Iran pose “a high level of risk to Israelis these days."

"Israeli citizens must remain vigilant and adhere to the necessary precautions when traveling to one of these countries,” the NSC statement said.

Israel's concerns stem from allegations in several media outlets that it was involved in the assassination of IRGC Colonel Hassan Sayyad Khodaei.
