SKorean president orders military on alert following ship blast
None
South Korea's president ordered the military on alert Tuesday for any moves by rival North Korea after the defense minister said last week's explosion and sinking of a South Korean ship may have been caused by a North Korean mine.
The blast ripped the 1,200-ton ship apart last Friday night. Fifty-eight crew members, including the captain, were plucked to safety; 46 are missing, with dim prospects for finding any further survivors. (AP)
