WASHINGTON — President Barack Obama spoke with Turkish President Tayyip Erdogan on Thursday about pressing issues in the Middle East, including the crisis in Yemen, the White House said. Turkey and the United States support the Saudi-led military operation against Houthi forces in Yemen, who have taken over much of the country in an effort to oust President Abd-Rabbu Mansour Hadi. Iran supports the Houthis. The leaders also discussed US-led negotiations over Iran's nuclear program, the White House said in a statement. The phone call came on a day when Erdogan complained at a news conference that "Iran is trying to dominate the region" and must withdraw forces from Yemen, Syria and Iraq. Obama and Erdogan discussed their cooperation fighting Daesh (self-proclaimed IS militants) and "common efforts to bring security and stability to Iraq and Syria," the White House said in a statement about the call. "The two leaders reviewed the train-and-equip program for vetted members of the moderate Syrian opposition. They discussed efforts to deepen cooperation to stem the flow of foreign fighters," the White House said. Obama "expressed appreciation for Turkey's continuing support to nearly two million refugees from Iraq and Syria," the White House said, noting they also discussed the crisis in Ukraine. - Reuters
