South Korean defense minister quits

Two days after the North Korean artillery attack, heads began rolling down in the government of South Korea and the first one was Defense Minister Kim Tae-young, who resigned on Thursday taking responsibility for the country's timid response.

The post-attacks scenario brought under scanner the role of defense ministry which failed to repel the attacks, though the nation vowed to retaliate the attacks.

North Korea shelled the island of Yeonpyeong, killing four people including two soldiers on Tuesday, setting several homes ablaze. On Thursday, it said it would stage more attacks if Seoul retaliates and defended its act as self-defense against the shelling of South Korea in its maritime waters.
