(Photos): Kim Jong-un throws a huge party for the scientists behind North Korea's latest nuclear bomb test

North Korean leader Kim Jong Un recently hosted a massive celebration to congratulate his nuclear scientists and technicians behind the country's sixth and largest nuclear test.

North Korea's official news agency confirmed that Kim and his wife, Ri Sol-Ju, gathered top scientists, including Ri Hong Sop and Hong Sung Mu, to celebrate what he called a 'perfect success in the test of H-bomb'.  

The blast, which came weeks after the country fired off two intercontinental ballistic missiles (ICBMs) that appeared to bring much of the mainland US into range, prompted global condemnation and calls to ramp up sanctions against the isolated nation.
