U.S. stocks closed down slightly on Thursday after the International Monetary Fund warned Greece ahead of its Sunday referendum that it faces a huge financial hole, and mixed jobs data dampened the U.S. economic outlook, Reuters reported. While the IMF was warning that Greece needed an extra 50 billion euros over the next three years to stay afloat, Greek Prime Minister Alexis Tsipras was urging voters to reject a bailout offer from lenders and saying he hoped to sign a new deal on Monday. -- SPA 00:08 LOCAL TIME 21:08 GMT تغريد
