The reunions, the first since February of last year, are a 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. About 390 South Koreans, some in wheelchairs, arrived Tuesday morning at a South Korean immigration office on the world's most heavily fortified border. "Have a nice trip," shouted South Korean Red Cross officials wearing yellow vests as the elderly men and women entered the immigration office in the border town of Goseong. 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.
