North Korea launched a barrage of around a dozen short-range ballistic missiles toward the sea separating Korea and Japan on Thursday. The missiles were fired from the Wonsan area toward the Sea of Japan, and it is believed they fell in waters outside Japan's exclusive economic zone.
The latest launches occur amid rising border tensions between the two nations. Seoul has accused Pyongyang of causing a landmine explosion last month that injured three soldiers, though North Korea denies the accusation.
Pyongyang has stepped up its weapons tests in recent weeks, despite South Korea's offer of military talks. The activity follows a visit to China by leader Kim Jong Un and comes at a time of uncertainty regarding potential nuclear talks with the United States.
