South Korea is boosting the number of troops on its islands close to North Korea after this week’s deadly artillery attack.
The parliament in Seoul passed a resolution condemning North Korea’s shelling of Yeonpyeong island and the deaths of two soldiers and two civilians. It stopped short of demanding immediate retaliation, but called for “firm and swift action” if there is any furthur attack.
Amid the rising tension, state media in Pyongyang has shown leader Kim Jong-il visiting a factory and a high school.
North Korea says it fired on the island on Tuesday because of a military exercise carried out near its territory, but Seoul denies it fired towards the North.
A US aircraft carrier has been sent to Korean waters, and China is under international pressure to deal with its close ally. Beijing is warning against what it calls “all military provocation”.
