Report sparks more speculation on Kim Jong Il's health
There is more speculation today about the health of North Korean leader Kim Jong Il, who hasn't been seen in public for several months.
Officials in South Korea and Japan have suggested that the 66-year-old suffered a stroke in August and would need considerable time to recover, but there has been no official confirmation.
Reports in South Korea today suggest he has suffered a serious setback and has been taken back to hospital.
Yesterday, Japan's Prime Minister told MPs in Tokyo that Kim was probably in hospital, but was still able to make decisions as North Korea's leader.
The chief of South Korea's National Intelligence Service also said yesterday that Kim was "not physically perfect", but still able to rule the country.
