South Korea's government has said there were no signs North Korean leader Kim Jong Un was gravely ill after reports he had undergone cardiovascular surgery earlier this month, and was in "grave danger".

Speculation over the state of his health was fuelled by his absence from a key anniversary event with the Daily NK, a speciality website run mostly by North Korean defectors, on Tuesday citing unidentified sources in the isolated state saying Kim was recovering at a villa in the Mount Kumgang resort after undergoing surgery on April 12.

CNN then reported Kim was in "grave danger".

Two government sources told Reuters news agency that reports Kim was in "grave danger" were not true, while the presidential Blue House said there were no unusual signs coming from the north.

North Korea marked the anniversary of the birthday of its founding father and Kim's grandfather, Kim Il Sung, as a national holiday on April 15, but there was no sign of Kim in the pictures shared by the state news agency.

Reporting from North Korea is notoriously difficult, especially on matters concerning the country's leadership.

Chad O'Carroll, the chief executive of Korea Risk Group, which produces the respected NK Pro and NK News, sounded a note of caution.

"It IS definitely notable that Kim Jong Un was missing all last week given the 04.15 holidays," he wrote on Twitter. "But it should be acknowledged that there are *many* rumours about his health going on at the moment. Some even regurgitate stuff we heard when KJU disappeared in 2014."

He noted that Kim had appeared in public three times in January and February and six times in March. So far in April, he has also appeared three times.

Overweight, smoker

Kim is heavily overweight and his health has deteriorated in recent months due to heavy smoking and overwork, the Daily NK said.

"My understanding is that he had been struggling [with cardiovascular problems] since last August but it worsened after repeated visits to Mount Paektu," a source was quoted as saying, referring to the country's sacred mountain.

Kim went into hospital after presiding over a meeting of the governing Workers' Party's Politburo on April 11, his last significant public event, the report said.

Pyongyang fired multiple short-range missiles last week which Seoul officials said were also part of the Kim Il Sung birthday celebration. Such military events would usually be observed by Kim, but there was no KCNA report on the test at all.-Al Jazeera
