A South Korean defense official says South Korea has returned fire after a North Korean artillery shell fell into waters near the two countries' maritime dividing line. Defense Ministry spokesman Kim Min-seok said Wednesday that North Korea fired three shells near the Northern Limit Line in the Yellow Sea. Kim says South Korean forces fired three shells back in response, according to a report of the Associated Press. South Korean forces have been on high alert in the area since a North Korean artillery attack killed four late last year.
