South Korea defence chief resigns following attack

South Korea’s defence minister resigned today amid intense criticism two days after a North Korean artillery attack killed four people on a small island near the Koreas’ disputed frontier.

The move came as President Lee Myung-bak vowed to send more troops to the frontline South Korean island of Yeonpyeong as residents tried to salvage belongings from the blackened wreckage of their homes. Pyongyang warned of additional attacks if provoked.
