North Korea has threatened to repeat its 2010 artillery attack on a border island, as South Korea prepares to mark the second anniversary of the shelling today that left four dead."The commemoration... on Yeonpyeong Island will lead to the second Yeonpyeong Island disaster," a military front man said.
The November 23, 2010 shelling of the island killed two South Korean marines and two civilians in one of the most serious border incidents since the 1950-1953 Korean War.
