South Korean protesters burn the pictures of North Korean leader Kim Jong Un during an anti-North Korea rally following a nuclear test conducted by North Korea, in Seoul, South Korea, Tuesday, Feb. 12, 2013.

The letters read " Support, U.N. sanction strongly and Out, Kim Jong Un." (AP Photo/Lee Jin-man)
