In North Korea, dictator Kim Jong Un has been making more public appearances with the person many believe will succeed him as supreme leader, his daughter Kim Ju Ae. NBC News' Raf Sanchez takes a closer look at her background.

North Korea's state media showed on Monday leader Kim Jong Un draping coffins with the national flag in what appeared to be the repatriation of soldiers killed fighting for Russia against Ukraine, as the countries marked a landmark military treaty.

Exports of luxury goods to North Korea are banned under U.N. sanctions but such items reportedly make their way into the country via diplomatic pouches.
