South Korea confirms North Korean nuclear test

HYUNG-JIN KIM Associated Press Published:

SEOUL, South Korea (AP) -- South Korea is confirming that North Korea has tested a nuclear device in defiance of U.N. orders to stop building atomic weapons.

South Korea's presidential security adviser Chun Yung-woo says Tuesday's nuclear test has been confirmed and that it cannot be tolerated. He provided no details on how Seoul confirmed the test.

A nuclear test could take North Korea closer to its goal of building a nuclear warhead that can be mounted on a long-range missile.
