North Korea has released images of special forces troops staging an attack on a mock-up of the Blue House, the South Korean President’s office. North Korean leader Kim Jong-un reportedly oversaw the training exercise that left the fake Blue House in flames according to state-run television KRT. South Korea’s parliament voted to impeach President Park Geun-hye on 9 December, and South Korea has been placed on high alert in case North Korea tries to take advantage.
