North Korea marked on Friday the third anniversary of an artillery attack on a South Korean island with a vow to respond to what it called any similar provocation with a strike on the South Korean presidential compound.
North Korea fired scores of artillery shells at South Korea’s Yeonpyeong island on November 23, 2010, killing four people including two civilians in one of the heaviest attacks on its neighbor since the Korean War ended in 1953.
It took many months for tension between the rivals to ease but it spiked again in March this year, during annual joint military exercises by the South and the United States. The North, which has conducted three nuclear tests, threatened nuclear attacks against the allies.
