The Joint Chiefs of Staff said on June 6, "North Korea launched two unidentified launch vehicles from the Hwanghae-namdo area to the East Sea early today."

"Our troops are maintaining their preparedness while monitoring and tracking the trends in preparation for additional launches," he said.

The launch of the launch vehicle was the fourth time in 13 days since the launch of a short-range ballistic missile projected last month.
