The International Atomic Energy Agency (IAEA) picked Argentine diplomat Rafael Grossi to become its next director general. Grossi, 58, was selected in the third round of voting against IAEA acting director general Cornel Feruta. He previously served as the chief of cabinet to former IAEA head Yukiya Amano and as a senior official at the Organization for the Prohibition of Chemical Weapons (OPCW) before becoming Argentina's ambassador to U.N. institutions in Vienna. Grossi also recently led an international review of the Non-Proliferation Treaty (NPT). Backed by the United States, Grossi pledged to strictly monitor Iran's nuclear activities. He is expected to begin a four-year term by January 1, 2020.
