N. Korea military, party vow loyalty to Kim Jong-Un
South Korean activists prepare to set alight an effigy of North Korean leader Kim Jong-Un during a protest rally in Seoul, on December 17, 2013
The vows of obedience, at an elaborate gathering in Pyongyang honouring Kim's father and former supremo Kim Jong-Il, followed the shock execution last week of the young leader's uncle and one-time political mentor Jang Song-Thaek.
Jang's purge raised questions about factional infighting at the top of the Pyongyang hierarchy and prompted both Seoul and Washington to warn of possible provocative acts by the nuclear-armed North.
State television showed tens of thousands of military and party officials sitting stony-faced in pin-drop silence for several minutes, before rising to greet Kim with thunderous applause as he took his place on the leadership podium.
"We should be warriors to safeguard the party centre with our lives... with the conviction that we know no one but the great comrade Kim Jong-Un," ceremonial head of state, Kim Yong-Nam, said in an opening address.
He added that the country had made "great strides" in the two years since Kim took over after his father's death.
Under Kim's leadership, North Korea has successfully placed a satellite in orbit and in February this year conducted its third -- and most powerful -- nuclear test.
The mass meeting also heard a keynote address by top military leader Choe Ryong-Hae, who some analysts believe had a hand in the ousting and execution of Jang -- long seen as the nation's unofficial number two.
The military will support "our supreme commander, under any storms and hardships", said Choe, a close Kim confidant who holds the military rank of vice marshal and is director of the Korean People's Army's General Political Department.
"We will share the fate with our respected supreme commander by living and dying with him until the very last moment," he said, while firing off a warning at rival South Korea.
"If the enemies drop a single drop of fire on our motherland, our soldiers will immediately storm out to wipe out all the invaders and achieve unification," he said.
At a meeting of top defence and national security officials on Monday, South Korean President Park Geun-Hye had warned that the recent leadership shake-up in the North could presage some aggressive behaviour.
"We can't rule out... reckless provocations," Park said, urging the military to step up vigilance along the heavily fortified border.
China, the North's sole major ally and key economic benefactor, said it would stay committed to promoting ties.
"The sound and steady growth of (China-North Korea) ties serves the fundamental interests of the two peoples and it also (has) positive implications to the peace and stability of Northeast Asia," said foreign ministry spokeswoman Hua Chunying.
There was no sign on the leadership podium of Kim Jong-Un's aunt and Jang's widow, Kim Kyong-Hui -- a major political player in her own right who holds the military rank of four-star general.
She had been named by state media at the weekend as attending an official function, suggesting she may have survived the purge of Jang associates.
The North's official Korean Central News Agency (KCNA) said Kim Jong-Un had visited his father's mausoleum on Monday, in the company of his wife Ri Sol-Ju.
Ri has not been seen since October, prompting speculation she may also have fallen out of favour.
Tuesday's meeting came the day after a massive military rally in Pyongyang, during which Choe urged troops to protect Kim Jong-Un "at the cost of their lives".
Jang's execution -- just days after he was ousted from all his party and military positions -- marked the biggest political upheaval since the younger Kim inherited power.
The purge was staged in an extraordinarily public and dramatic manner, with Pyongyang releasing images of Jang being dragged out of a party meeting.
Jang had been seen as Kim's political mentor but the 67-year-old's growing political influence and power was increasingly resented by the young leader, analysts said.
North Korea's state news outlets, meanwhile, have erased tens of thousands of articles archived on their websites, according to a watchdog site.
About 35,000 Korean-language articles have disappeared from the KCNA website, as well as 65,000 articles in Spanish, English, Chinese and Japanese, said Frank Feinstein, an analyst who tracks the North's online media for US-based website NK News.
About 20,000 articles were also removed from the archives of the Rodong Sinmun, the official newspaper of North Korea's Workers' Party, it said.
It was not clear if the deletion was permanent or related to efforts to eradicate Jang Song-Thaek's name from the official archive.
