The 50,000-year-old remains of a baby mammoth uncovered by melting permafrost have been unveiled to the public by researchers in Russia's Siberia region who call it the best-preserved mammoth body ever found.

The findings are unique because the mammoth's head and trunk survived all these years. The trunk typically thaws first and is eaten by birds.

Secretive North Korea has one of the world’s largest militaries, with 1.28 million active soldiers, but unlike in Russia, the Korean People's Army (KPA) has no recent experience of combat.
