Security Council on Tuesday addressing complex challenges facing the Middle East, Pompeo called for "fresh thinking" to solve "old problems." Some participants blamed regional and international powers, including the United States, for adding to the tensions in the region with their selfish unilateral moves. VOA's Zlatica Hoke reports.
