President Park Geun-hye held a rare meeting of top security officials Tuesday to discuss North Korea's recent test-firing of a submarine-launched ballistic missile, a South Korean official said.

The participants included Park's security adviser, the spy chief, the defense minister, the foreign minister and South Korea's point man on North Korea, spokesman Min Kyung-wook told reporters.

Still, Min did not give any further details of the meeting.

The meeting -- the first in a year -- came three days after North Korea claimed that leader Kim Jong-un oversaw a successful underwater test-launching of a "strategic submarine ballistic missile."

The Defense Ministry described the North's SLBM launch as "very serious and worrying," and urged Pyongyang to cease the development of such missiles. (Yonhap)
