A South Korean soldier stationed at a remote border outpost shot and killed five of his fellow soldiers, reports the BBC. He also wounded five others before fleeing the post with his rifle and ammo, an army spokesperson tells AFP. Authorities haven't speculated about a motive, but so far there's no indication that North Korea played a role in the rampage. It took place in Gangwon, specifically in Goseong County, described by Reuters as a mountainous region that borders the North on the eastern end of the Korean peninsula. (More South Korea stories.)
