Shelling by North Korea was 'inhumane crime' - Seoul

South Korean President Lee Myung-bak has described as an "inhumane crime" the North's deadly shelling of a South Korean island last week.

Mr Lee said he felt deep responsibility for failing to protect residents of Yeonpyeong, where two South Korean marines and two civilians were killed.

Pyongyang says it was provoked by Seoul's military drill near the island.

Tension remains high in the area, where the US and South Korea are currently holding joint military exercises.
