On the morning of May 18th, North Korea fired two short-range projectiles toward the East Sea, and one more in the afternoon. Another launch using a mobile launch vehicle came the next day.

The launch location is believed to be Hodo Peninsula near Wonsan.

Following the launches, the presidential office in Seoul convened a security meeting chaired by chief of the presidential National Security Office, Kim Jang-soo, and sought to grasp the intent behind the North's provocation.

The North had fired a short-range missile toward the East Sea on February 10th before conducting its third nuclear test. It also fired what's was initially believed to be a KN-02 ground-to-ground missile on March 15th.

But firing short range projectiles for two days straight is the first in 14 months since March 2012.

Despite the national security meeting chaired by Kim Jang-soo in the wake of the most recent launches, the presidential office did not issue any particular statement.

Presidential spokesman Kim Haeng only said the top office is keeping close tabs on the situation.

Meanwhile, the government has responded to the launches. A statement by the Unification Ministry condemned the launches and urged Pyongyang to stop provocations and accept talks with South Korea.

The U.S. has also responded. National Security Council Spokeswoman Caitlin Hayden said in a statement that North Korea has nothing to gain with provocations and will only further isolate itself from the rest of the world.

South Korean authorities believe the projectiles were likely KN-02 short-range missiles or a test fire of a 300-plus millimeter rocket launcher that the North is currently developing.

The KN-02 is a mobile missile that runs on solid fuel and an improved version of the Soviet's short-range SS-21 missile. Its maximum range is believed to be 160 kilometers.

If it's confirmed that the North test-fired a 300-plus millimeter rocket launcher, this would mean the emergence of a new weapons system that can threaten the area south of metropolitan Seoul.

Pundits believe through the provocation, the North again seeks to raise tension on the Korean Peninsula to draw U.S. and global attention.

But others are against reading too much into the latest launches, as the North typically fires short-range missiles several times a year.
