South Koreans look north at the Pyeonghwa (which means 'peace') Observation Post in Ganghwa, near the Military Demarcation Line separating the two Koreas, about 60km (38 miles) northwest of Seoul, November 11, 2009. Navies from the rival Koreas exchanged gunfire for the first time in seven years on Tuesday, damaging vessels on both sides and raising tension just days before U.S. President Barack Obama travels to Asia.
