PYONGYANG, North Korea — North Korea said Saturday that it successfully test-fired a newly developed ballistic missile from a submarine in what would be the latest display of the country’s advancing military capabilities.
Hours after the announcement, South Korean officials said the North fired three anti-ship cruise missiles into the sea off its east coast.
Experts in Seoul say the North’s military demonstrations and hostile rhetoric are attempts at wresting concessions from the United States and South Korea, whose officials have recently talked about the possibility of holding preliminary talks with the North to test its commitment to denuclearization.
For the second straight day, North Korea said it would fire without warning at South Korean naval vessels that it claims have been violating its territorial waters off the west coast of the Korean Peninsula. South Korea’s presidential Blue House held an emergency national security council meeting to review the threat.
“By raising tensions, North Korea is trying to ensure that it will be able to drive whatever future talks with the U.S. and South Korea,” said Yang Moo-jin, a professor from the Seoul-based University of North Korean Studies.
Security experts say that North Korea acquiring the ability to launch missiles from submarines would be an alarming development because missiles fired from submerged vessels are harder to detect before launch than land-based ones. North Korea has an arsenal of land-based ballistic missiles.
