SEOUL (Reuters) - North Korean leader Kim Jong Un was not gravely ill, two South Korean government sources said on Tuesday, following reports he had undergone a cardiovascular procedure and was now in "grave danger".

Kim was receiving treatment after undergoing the procedure, a South Korean media report said late on Monday, amid speculation over Kim's health following his absence from a key anniversary event this month.
