UPDATE on November 11/14:
There were three North Korean vessels and six South Korean warships on the scene. Two South Korean "patrol ships" (1.200 tons) and four "speed boats" (150 tons), all equipped with automatic cannons, were thus opposing three North Korean "garrison ships" (80, 130, 420 tons), all equipped with manual weapons. During the incident, it was the 130 tons North Korean garrison ship (Chinese "Shanghai class") that finally caught fire. Some days later, the North Korean side stated its firm will to resort to "severe measures" in order to protect its frontier aereas, and South Korea would have to pay a "high price" for that recent attack.
