朝鲜半岛再度传来隆隆炮声，使南北韩关系更加紧张。
韩国延坪岛上的居民星期五报告说，听到从邻近的北韩传来新的炮击声。
韩国军方官员说，没有炮弹落入韩国疆域。但是三天前，北韩炮弹击中延坪岛，致使两名韩国海军陆战队员和两名平民丧身，18人受伤。
与此同时，平壤方面态度更加强硬。北韩星期五警告说，南北韩更加接近“战争的边缘”。
The sound of new artillery fire is rattling the Korean peninsula, sparking a series of fresh warnings as tensions rise between the North and South.
Residents on the South Korean island of Yeonpyeong reported hearing the sound of shelling from nearby North Korea Friday.
South Korean military officials said no projectiles landed on South Korean territory, but the incident comes just three days after a North Korean artillery attack on the island killed two marines and two civilians, and wounded 18 other people.
The firing was accompanied by more tough talk from Pyongyang, which warned Friday the two nations are edging closer to "the brink of war."
