TWO South Korean marines and two civilians died after North Korea's shelling of one of 30 disputed islands, Yeonpyeong, housing a South Korean military base, on the border between the two Koreas. The borders were unilaterally drawn by the UN at the end of the 1950-53 war and the countries are still officially in a state of war. Rumours are that the incident is connected to the possible transition of power from North Korean leader Kim Jong Il to his son Kim Jong Un, or to North Korea's recent announcement that it is proceeding with its nuclear programme. The skirmish began Tuesday when North Korea warned the South to halt provocative military drills at the base, after which Seoul began firing artillery directly into disputed waters within sight of the North Korean shore. The North retaliated by shelling the Yeonpyeong military installations. Seoul responded by unleashing its own barrage of howitzers and scrambling fighter jets over the North, killing far more North Koreans though the actual number is not yet know. The words of condemnation -- of only the North -- from UN Secretary-General Ban Ki-Moon and US President Barack Obama flowed, as expected. Obama used the occasion to reaffirm plans to stage joint military exercises later this week in the Yellow Sea, the latest in its own provocations of both North Korea and China this year, following the sinking of a South Korean warship in an earlier joint US-South Korean military "exercise". Accusations that North Korea torpedoed the Cheonan, killing 46 sailors, were denied by Pyongyang and undermined by evidence pointing to the US itself. No definitive report has been issued. Four-hundred of the 1,700 residents of Yeonpyeong were evacuated. The South Korean government of pro-US President Lee Myung-bak who publicly opposes improved relations with the North, said that instead of demilitarising the disputed islands and agreeing to mediation, South Korea would strengthen its military forces there and halt aid to the communist North, while the North warned of more military strikes if the South encroaches on the maritime border by "even 0.001 millimetre". photos: Reuters
