North Korea Sends Fax to South Korea Warning it May Attack



North Korea has threatened to attack South Korea "without notice" in response to demonstrations held in the South to mark the anniversary of its former leader's death.

South Korea's Defense Ministry said a letter from the North's National Defense Commission was faxed early Thursday via a military communication link between the two sides, warning of a "merciless" attack on the South, The Wall Street Journal reported Friday. 

The letter objected to the "repeated extra-large provocations to North Korea's highest dignity taking place in the middle of Seoul" and threatened "a merciless retaliation without warning," ministry spokesman Kim Min-seok told the newspaper.
