Kim Jong-il health rattles neighbour

Sep 11 - South Korea is on alert for possible changes in the North after speculation Kim Jong-il suffered a stroke.

South Korea's president convened an emergency meeting of his cabinet to prepare for possible changes in North Korea.

Kim's death would create huge uncertainty over leadership in a country whose deep distrust of the outside world is backed by a 1.2 million-troop-strong army and possibly atomic weapons.

In a separate later development South Korean officials on Thursday declined to comment on media reports that North Korea was completing a new missle test site capable of launching long-range ballistic missiles.
