Nuclear Team to Visit Libya An inspection team from the United Nations" nuclear agency will visit Libya to assess the thousands of barrels of yellowcake uranium that reportedly are being stored at a former military site amid a "precarious" security situation in the country, a United Nations official said Monday. The International Atomic Energy Agency team will travel to Libya this month to "verify existing stockpiles and conditions of storage," said the official, Tarek Mitri, the secretary general's special representative to Libya. Mr. Mitri said United Nations authorities had received information "indicating that 6,400 barrels are stored" under the control of an army battalion near Sabha, in southern Libya, where militants and traffickers have roamed since the ouster of Col. Muammar el-Qaddafi in 2011. Yellowcake is concentrated natural uranium and the foundation material in the process to make nuclear fuel. Concerns about the material's storage have mounted as security in Libya has weakened.
