Seoul's Joint Chiefs of Staff(JSC) has denounced North Korea for its most recent ballistic missile launches.

During a briefing Tuesday, a South Korean JCS official addressed the North Korean missile launches earlier in the day, calling them "grave provocations" that put South Korea and its citizens at risk. 

North Korea fired three short-range ballistic missiles into the East Sea on Tuesday morning. 

The JCS official said the projectiles are presumed to be short-range Scud or mid-range Nodong missiles. Two of the three missiles flew around 500 to 600 kilometers. The South Korean military is said to be analyzing the trajectory of the other projectile.

Japan's Kyodo News reported the U.S. Strategic Command as claiming two of the three projectiles were believed to be Scud missiles and one was a Nodong.

The over 500-kilometer trajectories of the projectiles are an apparent show of the North's capability to send its missiles to South Korea's southern region, where the U.S. THAAD missile interceptors are planned to be located. 

The launches came in less than a week after the South Korean government revealed the southern location of the U.S. missile interceptors.
