Kim Jong-Un had uncle stripped naked, thrown into a cage and eaten alive by dogs A pack of 120 starving dogs were set on Jang Song Thaek and five aides Kim Jong-Un and 300 officials watched horrific execution Punishment, called 'quan jue', or execution by dogs, lasted an hour Uncle was accused of treachery and corruption by the brutal regime Kim has carried out a 'massive purge' of threats to consolidate his grip North Korean dictator Kim Jong-Un sentenced his uncle to be eaten alive by a pack of 120 wild dogs in a savage punishment for treachery, it has been claimed. Jang Song-Thaek, 67, along with five close aides, was stripped naked and thrown into a cage of hounds which had been starved for three days, according to new details emerging from China. The pack of animals spent more than an hour mauling the group in a punishment called 'quan jue', or execution by dogs, a report in Chinese newspaper Wen Wei Po said. Brutal: Jang Song-Thaek, in blue suit and handcuffs being escorted in court on December 12, was executed by wild dogs, according to reports coming from China The tyranical leader of the communist state had accused his uncle - once seen as North Korea's second most powerful man - of treason and corruption and described him as 'scum' and 'factionalist filth' during his recent New Year message. Unlike previous executions of political prisoners, which were carried out by firing squads with machine guns, this extraordinary sentence seems to have been specially reserved for the most hated in North Korean society. The report in the Chinese language newspaper said the entire process was supervised by the supreme leader in North Korea, along with 300 senior officials - a clear warning against anyone challenging Kim's leadership.

The fact details of the barbaric punishment emerged in a newspaper, viewed as Beijing Government's official mouthpiece, in Hong Kong, has been seen as another signal of China's authorities losing patience with its wayward neighbour, according to The Straits Times. Kim Jong-Un spoke of the execution of his 67-year-old uncle during his New Year address telling the country 'our party took resolute action to remove...scum elements within the party last year.' The 30-year-old leader appeared on state television for the speech and analysts say the words reflect his feelings towards aides of his uncle, Jang Song-Thaek, and other family members who are believed to have been sent to labour camps.

Some say he was seen as a threat In its announcement of the sentence, the North Korean regime described Jang as "despicable human scum," who was "worse than a dog." Furthermore, he "perpetrated thrice-cursed acts of treachery in betrayal of such profound trust and warmest paternal love shown by the Party and the leader for him." His supposed crimes against the regime included having "improper relations with several women" and having "wined and dined at back parlours of deluxe restaurants." In addition, Jang was said to have "squandered foreign currency at casinos while he was receiving medical treatment in a foreign country under the care of the party." Worst of all perhaps, in the twisted logic of this supposed workers" paradise, was that Jang was guilty of "such factional acts as dreaming different dreams." Revelations: Kim Jong-un used his New Year's speech to defend the recent execution for treason of Jang Song-thaek, Kim's uncle and North Korean second most powerful man of the past decades Authoritarian: North Korean leader Kim Jong-un (seventh from the right) visits the mausoleum of his father Kim Jong-il, late North Korean leader, at Kumsusan Palace of the Sun in Pyongyang on New Year's Day 'If the war breaks out again in this land, it will bring about a massive nuclear disaster and the US will never be safe,' he warned. Kim took a test ride on a ski lift, rising up over the project that he said during an earlier visit was 'at the centre of the world's attention'. Kim Jong-Un is no stranger to ordering brutal crackdowns on anyone even suspected of posing a political threat - no matter how close the relationship. The dictator had his former lover singer Hyon Song-wol, pictured right, executed by machine gun amid claims that she had been appearing in pornographic videos. Hyon was among a dozen singers, musicians and dancers from two pop groups who were machine-gunned to death on August 20, last year. The savage death of Kim's uncle sent shock waves through the authoritarian state, showing no one was safe - even family members. Kim's teenage nephew fled to a university campus in Paris after the execution of Jang Song-Thaek. The 19-year-old's name was removed from the postbox at prestigious social science university Sciences-Po, which saw South Korean media report that he was hiding for fear of his safety. Fears also mounted last month that Kim's wife Ri Sol-Ju had fallen out of favour with the tempestuous leader. She had not been seen publicly for weeks and was not present in an official photograph, provoking speculation But these were largely eased when a video was released showing her with Kim Jong-Un at a memorial service to mark the second anniversary of his father's death.
