BRUSSELS (Reuters) - Turkish Foreign Minister Mevlut Cavusoglu said on Wednesday that it would be a  grave mistake  for the United States to move its embassy in Israel to Jerusalem and that he had warned U.S. Secretary of State Rex Tillerson. Before a bilateral meeting with Tillerson at NATO headquarters, Cavusoglu said:  It would be a grave mistake (to move the U.S. embassy). It will not bring any stability ... but rather chaos and instability.   The whole world is against this,  he said, adding that he had already told Tillerson how he felt and would reiterate it at the meeting at NATO during the alliance s foreign ministers  meeting.
