Kim Jong-un has been seen with a mysterious head bandage like a large plaster, fuelling further concerns for his health.
North Korean's tyrant was earlier spotted with unusual dark patches above his neck.
Footage of a military conference held in Pyongyang from July 27 to 29 - but released today - shows the leader with a big plaster as he addresses the crowd.
In a further clip of the recent state TV broadcast, Jong-un was seen with the apparent wound uncovered.
It comes amid speculation about the 37-year-old's well being following his dramatic recent weight loss.
Last week, North Korea aired unprecedented television footage of one of its citizens expressing concern for the dictator.
The Supreme Leader's health status is usually off-limits - but state TV allowed the country's main channel to show footage of him looking thinner.
The BBC reports that viewers of tightly-controlled Korea Central Television saw a clip of Jong-Un arriving at a concert.
The channel then aired a video of a Pyongyang citizen telling the channel about his upset at seeing Jong-un look so thin.
The man said: "Seeing him become emaciated like that, we all became so sad. Everyone just started to cry."
It comes as the leader's sister warned the US and South Korea not to hold “hostile” military drills this month in a show of her rising power in North Korea.
Kim Yo-jong says North Korea will be watching closely to see if the annual “war exercises” take place and that they would damage “North-South” relations.
The US and South Korea hold a military drill each year which they have previously said is for defence reasons.
Following positive steps between the two countries, communication channels were reopened.
But Yo-jong said moves towards a better relationship could be about to be undone.
"Our government and military will keep a close eye on whether the South Koreans go ahead with the aggressive war exercises, or make a big decision," Yo-jong said in a KCNA statement.
"Hope or despair? That's not up to us."
Yo-jung is rumoured to be seen by Kim as his successor should he die before his son, 12, is old enough to take to power.
After Joe Biden was elected US president earlier this year, she quickly sent a warning to him.
"We take this opportunity to warn the new US administration trying hard to give off powder smell in our land," she said.
"If it wants to sleep in peace for coming four years, it had better refrain from causing a stink at its first step."
