North Korea resumed firing artillery Thursday near its disputed western sea border with South Korea, an official said, a day after the country fired dozens of shells and prompted South Korea to fire back a barrage of warning shots.
North Korea fired several rounds of artillery toward the border early Thursday and the shells are believed to have landed in NorthKorean waters, an official at the Joint Chiefs of Staff said. Theofficial, speaking condition of anonymity citing department policy,said South Korea didn't respond.
The poorly marked sea border is a constant source of tension between the two Koreas, with their navies fighting a bloody skirmish in November that left one North Korean sailor dead and three others wounded. They engaged in similar bloody skirmishes in 1999 and 2002.
