North Korean television showed the body of late leader Kim Jong-Il lying in state in a glass coffin Tuesday as his son and successor Kim Jong-Un and other senior officials paid their respects.

North Korean TV footage shows Kim Jong-Il's body lying in state in glass coffin in Pyongyang.

The body of Kim senior was dressed in his trademark khaki tunic, with most of the corpse covered by a red sheet, at Pyongyang's Kumsusan Memorial Palace.

The body of Kim Jong-Il's father, founding president Kim Il-Sung, is also on display elsewhere in the palace.

"Comrade Kim Jong-Un... paid a visit to the body of comrade Kim Jong-Il with party, government and military officials and expressed condolences with the deepest sorrow," the official news agency said.

State media have reported scenes of mass grief since Kim's death at the age of 69 was announced Monday. He had died two days earlier of a heart attack during a train trip.

The North has set the funeral for December 28 and urged people to rally round the son as "great successor".
