Delly Mawazo Sesete wants American consumers to know what is in their smart phones, computers and other electronics and where U.S. companies like Apple are getting those rare metals.

Sesete says that, without knowing, consumers in the U.S. could be fueling conflicts in Eastern Congo. The human rights activist is from a remote part of the Democratic Republic of Congo, where armed groups are wreaking havoc and get much of their funding from mining rare metals.

The changing of the guard in North Korea poses clear risks for the United States.

Kim Jong Il's son, Kim Jong Un, looks to be the likely successor. But he's still in his 20s and has had little time to prepare to take over the country. Analysts say that because he's weak, he won't be in any position to get back to nuclear disarmament talks and make concessions.

As the final U.S. troops leave Iraq, they leave behind the largest U.S. Embassy in the world.

There will be about 16,000 people working for the State Department at the embassy in Baghdad and consulates elsewhere in Iraq.

South Sudan, the world's newest nation, is still trying to find its feet, and private companies, international aid experts and diplomats have gathered in Washington this week to see if they can help.

Secretary of State Hillary Clinton has just completed a trip to Asia, including a historic visit to Myanmar. That country, also known as Burma, has been subjected to international isolation for many years because of its brutal military dictatorship. Now there are signs that a new civilian regime is loosening the generals' grip. NPR's Michele Kelemen accompanied Clinton on her visit, and filed this Reporter's Notebook.
