In a photo released by North Korea's Korean Central Agency, North Korean leader Kim Jong Un (third from right) and other senior leaders attend a memorial service in Pyongyang, March 25, marking the 100th day since the death of Kim's father, Kim Jong Il. North Korea has been sending the world mixed messages since the death of the elder Kim.
North Korea is the most secretive country in the world. Its pursuit of nuclear weapons is a cause of great concern all over the world, and just this week, the country tested two short-range missiles soon after President Obama left the region after attending a nuclear summit. United States has suspended food aid to that regime in response to North Korea's planned long-range missile test later this year.
With a new leader in North Korea, the U.S. and South Korea are watching for clues of his policies. But so far tensions have not eased along the demilitarized zone. Here, two North Korean soldiers look across at a South Korean soldier on Dec. 2.
North Korea agreed, last month, to freeze uranium enrichment and missile tests in exchange for large amounts of food aid from the United States. American officials thought they had an understanding, but then last week North Korea announced it would be launching a satellite using a long-range missile. As NPR's Mike Shuster reports from Seoul, all this is now threatening to overshadow next week's global nuclear security summit in Seoul, which President Obama is planning to attend.
