An anti-North Korea activist prepares to release a balloon carrying anti-North Korea leaflets towards the north at a village, near the border separating the two Koreas in Ganghwa, about 60km (38 miles) west of Seoul, July 3, 2009. The activists denounced the North's missile launch and released about 100,000 anti-Pyongyang leaflets on Friday. North Korea may test mid-range missiles or fire more short-range missiles to step up sabre rattling that has raised regional tension, a South Korean daily said.
