North Korea Threatens South Korea... By Fax The North Korean military this week warned it might "ruthlessly" attack South Korea, and it sent the threat by fax. A South Korean news agency reported Friday that the message was sent in response to rallies held in Seoul on Tuesday, where protesters criticized the North's authoritarian rule by burning photos of Kim Jong Un, the country's dictator. The attack could come "without any notice," the menacing fax stated. Despite the threat, South Korean officials said they had not detected unusual military activity in the North. Indeed, the North has a history of threatening military action and not following through. A spokesperson from South Korea's defense ministry said the country was prepared to "sternly react" to any military provocations from the North.
