Members of North Korea Peace, an international volunteer group helping North Koreans, fly balloons with boxes containing pairs of socks towards North Korea near the demilitarized zone separating the two Koreas in Paju, about 50 km (32 miles) north of Seoul, December 24, 2011. The volunteer group sent 1,000 pairs of socks stapled with messages of hope and love to North Korea via inflated balloons on Saturday. According to them, the warm socks are a critical necessity during severe winter season in North Korea, where many people lose their foot and legs due to frostbite. The socks can be exchanged for approximately 22 pounds of corn in the local market, enough food for one month. REUTERS/Kim Kyung-Hoon (SOUTH KOREA - Tags: POLITICS MILITARY)
