South Korean soldiers patrol near the demilitarized zone separating the two Koreas in Goseong, about 330 km (205 miles) northeast of Seoul, February 16, 2009. With figure skaters, strange weather patterns, a fresh missile threat and ageing cadres praising a "peerlessly great man", North Korea celebrated leader Kim Jong-il's 67th birthday on Monday. While the North basked in festivities for Kim, who suffered a suspected stroke in August but appears to have recovered, the region was on edge over a possible missile launch. REUTERS/Lee Jae-Won

A South Korean soldier shot and killed five fellow soldiers and wounded five others at a border post near North Korea on Saturday night, reports Associated Press.

The conscript army sergeant opened fire near Goseong, Gangwon Province, and then fled with the rifle and ammunition, Yonhap News reports. A spokesman for South Korea's Defense Ministry would not confirm that the soldier was still at large, but Yonhap says there was an operation to capture the missing soldier late Saturday night.

The soldier, identified as having the surname Lim, was a part of the 22nd Infantry Division.

South Korean officials do not suspect North Korean involvement.
