North Korea launched a ballistic missile off its east coast on Monday, South Korea's military said, a day after the North vowed "offensive and overwhelming" responses to protest a new U.S. military drill with South Korea and Japan.
On Sunday, North Korea's Foreign Ministry issued a lengthy statement strongly denouncing the U.S., South Korea and Japan over their three-way drill.
Last Wednesday, North Korea launched what it called a multiwarhead missile in the first known launch of a developmental, advanced weapon meant to defeat U.S. and South Korean missile defenses.
North Korea said the launch was successful, but South Korea dismissed the North’s claim as deception to cover up a failed launch.
In recent weeks, North Korea has floated numerous trash-carrying balloons toward South Korea in what it has described as a tit-for-tat response to South Korean activists sending political leaflets via their own balloons.
