President Lee Myung-bak Monday canceled all planned schedules over North Korean leader's death, while the Joint Chiefs of Staff (JCS) on Monday placed all military units on emergency alert following the news of North Korean leader Kim Jong-il's death.
The JCS said it called an emergency meeting of officials handling crisis management and operations just after noon Monday, after the North Korean media reported Kim's death.
The JCS said it has increased its monitoring activities along the border along with the South Korea-U.S. Combined Forces Command.
No unusual activity had been observed from the North, officials said.
Officials said they may raise the "Defcon," a five-stage combat alert level, from its current level of four to three. (Yonhap)
