South Korea's military said North Korea on June 8 test-fired apparent land-to-ship missiles from the North Korean coastal city of Wonsan, Reuters reported.

The United Nations Security Council recently expanded existing sanctions on North Korea, strongly condemning the country's nuclear weapons and ballistic missile development program, under which it has conducted 10 missile tests in 2017, including the one on May 29, defying threats of further sanctions being considered by the U.S., China, South Korea and Japan.

Bloomberg News reported, citing Kyodo News, that the rockets landed short of Japan's economic zone, having traveled about 200 kilometers.

South Korean President Moon Jae-in, who had said he was open to dialogue with North Korea, has been informed about the latest launch, South Korea's Office of Joint Chiefs of Staff said, according to the Reuters report. Pyongyang has conducted four missile tests since South Korea's newly elected president took office in early May.

The latest test comes soon after Moon suspended the installation of remaining components of a controversial U.S. missile shield, called the Terminal High Altitude Area Defense, saying South Korea will assess the impact of the system on environment, a process that may take as long as a year, Bloomberg News reported, citing Yonhap News Agency, which in turn cited "a senior official" at the president's office.
