WASHINGTON (AP) — A State Department official says the United States won't attend a multinational peace conference on Afghanistan next month in Russia. The reasons: The U.S. wasn't consulted before receiving the invitation and doesn't know Russia's objectives for the gathering. The official wasn't authorized to speak publicly on the matter and demanded anonymity. The official said Thursday that Washington wants to work with Moscow on regional efforts to end the 16-year war, and that Secretary of State Rex Tillerson would bring up the matter when he visits Russia in April. Afghanistan, Pakistan, Iran, India and several Central Asian nations are among the invitees to the Moscow conference.Read more on NewsOK.com
