South Korea will stage naval firing drills at 23 venues from tomorrow but will exclude areas near the disputed sea border with North Korea. South Korea's Joint Chiefs of Staff today said the military plans to stage live-fire drills of the coast around the Korean peninsula from tomorrow to Friday. He said the firing exercise will not be held near the tense maritime border with the North on the Yellow Sea. A spokesman of the Joint Chiefs of Staff said this is part of a regular practice involving army, naval and air forces and the state-run Agency for Defence Development will also conduct ammunition tests off the west coast. Seoul on December 20 staged a live-fire artillery exercise on Yeonpyeong island, a border island that was shelled by the North in an attack that killed four South Koreans, including two civilians.
