North Korea is urging its people to rally behind Kim Jong Il's young son and heir-apparent Kim Jong Un. The world is watching warily for signs of instability in a nation pursuing nuclear weapons.
South Korea has put its military on high alert against the North's 1.2 million-strong armed forces. President Barack Obama agreed by phone with South Korean President Lee Myung-bak to closely monitor developments.
