North Korea posted this ISIS-style video showing a mock missile attack on Guam
Displaying images of Donald Trump staring at a cemetery filled with crosses and Vice-President Mike Pence enveloped by flames, the nearly four-minute video showed the island of Guam being targeted by intermediate-range ballistic missiles.
"Americans should live with their eyes and ears wide open. They will be tormented day and night by the Hwasong-12 rockets without knowing when they will be launched," the caption reads, according to Yonhap. "They will be in jitters."
"(We) just wish US policymakers should seriously think twice ahead of an obvious outcome (of a war)," another caption says, showing a photo of US Defence Secretary James Mattis. "Time is not on the US side."
With the exercises continuing on Aug. 22, upped its rhetoric, saying it would be a misjudgment for the US to think that Pyongyang would "sit comfortably without doing anything," the state-run Korean Central News Agency said, citing an unidentified military spokesman.
The ongoing drills and visits of US military officials to South Korea create the circumstances for a "mock war" on the Korean peninsula, KCNA said.
The comments represent a more belligerent tone after a war of words between the US and appeared to have subsided.
Trump praised North Korean leader Kim Jong-un last week for waiting to launch missiles over Japan into waters near Guam, after previously warning of "fire and fury" if he continued to threaten the American homeland.
Tensions increased in July after conducted two intercontinental ballistic missile tests. Trump has said military force is an option to prevent Kim from gaining an ICBM that could deliver a nuclear weapon to the US.
On Monday, South Korea President Moon Jae-in said shouldn't use the latest round of drills as an excuse for any further provocations. The exercises "are not aimed at raising military tensions on the Korean peninsula at all," Moon told Cabinet members.
Kim made a visit in early August to a guard post about 1 kilometer (0.6 miles) from the border with the South, Yonhap News reported, citing unidentified South Korean government officials. The South Korean military considers the visit an unusual act and is preparing to prevent a possible military provocation, Yonhap said.
