A South Korean tourist views a 3D panorama of scenes from the Korean War at the 'Museum to Commemorate the War to Resist US Aggression' at the Chinese city of Dandong on February 8, 2013. US Secretary of State John Kerry warned that North Korea's expected nuclear tests only increase the risk of conflict and would do nothing to help the country's stricken people. The country has vowed to carry out a third nuclear test soon, and concerns have been raised over the type of fissile material used in the device.
