South Korea and the United States will conduct a mock attack on a nuclear facility next month, an official with the South Korean Defense Department told CNN.

Though the official said the drills are not aimed particularly at North Korea, the announcement comes less than two weeks after North Korea claimed to have successfully tested a nuclear warhead — its second nuclear test this year and fifth one ever.

The test prompted a strong rebuke from the international community, with South Korea saying it was “getting ready for the worst case scenario.”

The simulation, dubbed joint exercise “Red Flag,” will take place in Alaska from October 3 until October 21.
