The Israeli government issued an unequivocal travel advisory on Monday warning Israelis to avoid visiting Turkey, a popular vacation destination for Israelis over the summer and during the upcoming Jewish holidays, Israel Hayom reported.

The Prime Minister’s Office issued its routine semi-annual travel warning, formulated by the office’s Counterterrorism Bureau, stating that all non-essential visits to Turkey “should be avoided.”

The threat issuing from Turkey is defined as an “ongoing potential threat,” a mid-level threat on the bureau’s five-level scale. Turkey is now on the same threat level as countries where jihadi terror cells are known to be operating, including Nigeria, Kenya and Azerbaijan.

The travel warning is for the upcoming Jewish holidays in September. So far, over the summer months of July and August, tens of thousands of Israelis have visited Turkey.

The Counterterrorism Bureau also recommended that Israelis avoid visiting the two countries with which Israel shares a border and a peace agreement: Egypt and Jordan. In those two countries, the threat facing Israelis was defined as a “basic concrete threat,” one level higher than the threat facing Israelis in Turkey. For Morocco, another popular destination for Israelis, an “ongoing potential threat” warning was issued.
