N. Korea Tests U.S. Deal Ahead Of Nuclear Summit
North Korea's nuclear weapons program is threatening to overshadow the global Nuclear Security Summit in Seoul next week. Last month, North Korea said it would freeze its enriched uranium weapons program and its long-range missile activities in exchange for U.S. food aid. But a few days ago, North Korea announced plans to launch a satellite in April, which the U.S. says is counter to the agreement made last month. Now prospects for the deal are uncertain.
