US President Trump says he "does not respond to short-range missiles" in connection with North Korea's launch.

At a visit to the National Institutes of Health Vaccine Research Center near Washington, DC, Trump responded to a question about North Korea's response to missile launches.

President Trump did not react particularly when North Korea launched a series of short-range ballistic missiles last year.

North Korea's Chosun Central News Agency reported that the projectile launched yesterday was a super-sized gun.

South Korean military has analyzed the projectiles as short-range ballistic missiles.
