The United Nations Security Council strongly condemned North Korea for test-firing ballistic missiles and agreed to take "significant measures" in response to the latest series of launches.
The 15-member council on August 26 issued a toughly worded condemnation in a unanimous statement drafted by the United States and backed by China, Pyongyang's main ally.
North Korea has been hit by five sets of UN sanctions since it first tested a nuclear device in 2006.
In March, the council adopted the toughest sanctions to date, targeting North Korea's trade in minerals and tightening banking restrictions.
The council met after North Korea launched a missile from a submarine towards Japan on August 24.
Japanese Prime Minister Shinzo Abe said the missile breached Japan's air defense zone and called it an "unforgivable, reckless act."
The council condemned that launch as well as another on August 2 that for the first time fell in Japanese-controlled waters and two other missile tests on July 9 and 18, saying these were all "in grave violation" of UN resolutions.
North Korea leader Kim Jong-Un boasted that the submarine-launched missile was his "greatest success," putting the U.S. mainland "within striking range."
