A South Korean military drill under way on the country's northern-most island of Baengnyeong against a presumed North Korean bombardment and violation of the Northern Limit Line, an inter-Korean maritime border in the West Sea.

The Washington- based Institute for Science and International Security had estimated last year that North Korea had 10 to 16 nuclear weapons at the end of 2014.
