Thousands of Israeli tourists are failing to heed warnings on travel to Turkey.



The warning published by the anti-terror agency says that “severe, concrete threats” have been uncovered. The warning strongly recommends that Israelis avoid visiting the entire southern coastal area of Turkey.



As many as 200,000 Israelis are expected to visit the coastal region this time of year.



Terrorists have already established a significant presence in Turkey. Three laboratories for manufacturing explosives belonging to al Qaeda have been uncovered, and two terrorists blew themselves up Monday in an terror-related accident in Istanbul.



Turkish authorities believe that investigations will reveal a more extensive terrorist infrastructure in that country.



Israel's anti-terror agency said, however, that the warning was temporary and would be rescinded once the threat is eliminated. Israel’s ambassador to Turkey, Yosef Aviv, also emphasized the temporary nature of the warning.



Besides the travel advisory against visiting Turkey’s southern shore, the agency is also warning Israelis not to visit areas bordering Iran or Iraq.



Monday, the agency diverted an Israeli ship bound for Turkey to Cypress, as a result of the security threat. Thus far, five Israeli tourist ships have been diverted to Cypress.



The Ministry of Transport has ordered that the points of anchorage of Israeli ships in Turkish ports be changed in order to thwart potential terrorist attacks.
