A group of men work at clearing a container hidden on the North Korean flagged ship Chong Chon Gang, docked at the pier in Manzanillo, Colon, Panama, July 16, 2013. The ship was carrying missile system components hidden in a cargo of sugar and authorities presume that there may be more 'military equipment' similar to the one seized. North Korean freighter was travelling from Cuba toward the Panama Canal and back to its home country. [Photo/CFP]
