N Korea leader 'visits library'

North Korea has released more photos of leader Kim Jong-il, this time visiting a library, as speculation continues about his health.

The images show Mr Kim, in a brown fur hat and trademark sunglasses, looking at people using computers during a visit to the northern Jagang province.

South Korean and US officials say Mr Kim suffered a stroke in August but North Korean officials deny he is ill.

No proof of date has been provided with any of the images released.

Some have also queried the authenticity of the images.

The 66-year old leader, who is reportedly suffering from heart disease and diabetes, has not been seen at key events in recent months.

But in the latest in a series of photos apparently meant to show that Mr Kim is in good health, KCNA published several photos of him said to be on an official visit.

The leader was also reported to have visited a computer software centre, but KCNA did not say when either visit had taken place.

On Friday, the agency reported Mr Kim had toured chicken farms.

Mr Kim's reported illness comes as international negotiations continue over North Korea's nuclear programme.

North Korea said last year it would give up its nuclear programme in return for aid and diplomatic concessions but progress towards dismantling its Yongbyon nuclear reactor has been patchy.
