North Korea - online puzzles

North Korea, officially the Democratic People 's Republic of Korea (abbreviated as DPRK, DPR Korea or Korea DPR), is a country in East Asia constituting the northern part of the Korean Peninsula. Pyongyang is the nation's capital and largest city. To the north and northwest, the country is bordered by China and by Russia along the Amnok (known as the Yalu in China ) and Tumen rivers; it is bordered to the south by South Korea, with the heavily fortified Korean Demilitarized Zone (DMZ) separating the two. Nevertheless, North Korea, like its southern counterpart, claims to be the legitimate government of the entire peninsula and adjacent islands. Both North Korea and South Korea became members of the United Nations in 1991.

In 1910, Korea was annexed by Imperial Japan. After the Japanese surrender at the end of World War II in 1945, Korea was divided into two zones, with the north occupied by the Soviets and the south occupied by the Americans. Negotiations on reunification failed, and in 1948, separate governments were formed: the socialist Democratic People 's Republic of Korea in the north, and the capitalist Republic of Korea in the south. An invasion initiated by North Korea led to the Korean War (1950–1953). The Korean Armistice Agreement brought about a ceasefire, but no peace treaty was signed.
