North Korea fired two rounds toward South Korea at their tense border and South Korean troops immediately fired back, an official said today. There were no South Korean injuries and it was unclear whether it was an accident or an intentional provocation, said an official at the Joint Chiefs of Staff in Seoul. The firing came hours after the North vowed to retaliate against South Korea for its rejection of a North Korean proposal for military talks.
The exchange of fire at the heavily armed border highlights the security problems faced by Seoul as it prepares to host the Group of 20 economic summit next month. (More Korea stories.)
