Hijjah, 1431/Nov 26, 2010, SPA -- South Korean President Lee Myung-bak on Friday named his new defense minister, replacing Kim Tae-young who quit following criticism of a slow response to an artillery attack by North Korea, as Reuters reported. The presidential Blue House appointed Kim Kwan-jin, 61, former chairman of the joint chiefs of staff. Four people were killed when North Korea lobbed scores of artillery shells on a South Korean island near the disputed sea border on Tuesday.
