As if the normal run of security headaches were not enough, South Korean officials are now worried that North Korea might try to flood out the 1988 Summer Olympic Games in Seoul.

That's why South Korea is speeding up construction of a dam near the mideastern border with its neighbor to the north to ensure safety for the 161-nation 24th Summer Olympics that start Sept. 17.Seoul says its "Peace Dam," as it is called, should counter a threat posed by a dam the North Koreans are building on their side of the contentious border.

In this latest round of saber-rattling between the two Koreas, the south says the northerners' dam could release an enormous amount of water that could flood and knock out Olympic facilities in South Korea's metropolitan areas.
