About 390 South Koreans, some in wheelchairs, others leaning on walking sticks, made their way through an immigration office in Goseong, a South Korean town on the world's most heavily fortified border. In a second round, from Saturday until Monday, about 250 South Koreans are to visit the mountain resort to reunite with about 190 North Korean relatives, the Unification Ministry said. The reunions, the first since February of last year, are a poignant yet bitter reminder that the Korean Peninsula is still in a technical state of war because the 1950-53 fighting ended with an armistice, not a peace treaty. The Koreas bar ordinary citizens from visiting relatives living on the other side of the border and even from exchanging letters, phone calls and emails without government permission. The rivals in August agreed to resume family reunions during talks to end a standoff caused when land mine blasts blamed on Pyongyang maimed two South Korean soldiers. South Korea uses a computerized lottery system to pick participants while North Korea reportedly chooses based on loyalty to its authoritarian leadership.
