North Korea released a video Monday that depicts an attack on South Korean government buildings, including the presidential Blue House. The 88-second video is called “if the ultimatum goes unanswered” and ends with the words “everything will turn into ashes.” Over the past several weeks, the country has repeatedly issued threats against Seoul and Washington, largely in response to annual joint military exercises that began in early March. The Korean People’s Army has issued an “ultimatum” demanding South Korean President Park Geun-Hye apologize for the larger-than-usual war games, which include an operation built to “decapitate” Pyongyang’s leadership, should a full-scale conflict arise. A little more than a week ago, the website released a video showing a nuclear attack on the United States.
