Seoul put South Korean forces on high alert and Pyongyang urged an increase in its "military capability" as the death of North Korea's leader Kim Jong Il spurred fresh security concerns in the tense region.
(CNN) Seoul - A tearful state TV broadcaster reported Kim's death Monday. She said the 69-year-old leader died Saturday due to "overwork" while "dedicating his life to the people."
North Korea's official KCNA news agency said Kim suffered "great mental and physical strain" while on a train. Kim, who had been treated for "cardiac and cerebrovascular diseases for a long period," suffered a heart attack on Saturday and couldn't be saved despite the use of "every possible first-aid measure," according to the agency.
In the country where Kim was revered as "dear leader," passers-by wept uncontrollably on the streets of Pyongyang.
"My leader, what will we do? It's too much! It's too much!" one person sobbed. "Leader, please come back. ... You cannot leave us. We will always wait for you, Leader."
