North Korea marked the birthday of its founder on Sunday with a massive celebration featuring military musicians and singers performing beneath images that included a simulated missile attack on the United States.

Footage from North Korean state-run TV showed leader Kim Jong Un in attendance at the celebration of the 105th birthday of his grandfather, Kim Il Sung, who died in 1994.

About 1 hour and 13 minutes in, video screens in the concert hall highlighted various North Korean weapons, including missiles being launched. Eventually, the footage changed to computer graphics showing several missiles destroying a city.

The city wasn’t named, but one of the images featured a tattered American flag over a cemetery, with the entire scene engulfed in flames:

North Korea has a history of bellicose statements and videos, with many of them directed at the U.S. One video released last year depicted a nuclear attack on Washington, D.C.

The latest footage was released amid escalating tensions between Washington and Pyongyang -- and just days after a failed missile test in North Korea. But the troubled nation may not be done showing off its arsenal.

“We’ll be conducting more missile tests on a weekly, monthly and yearly basis,” Vice-Foreign Minister Han Song-ryol told the BBC on Tuesday.

In an interview broadcast on Fox News, President Donald Trump was asked what the U.S. would do in response to additional weapons tests in North Korea.
