President Moon Jae-in has slammed Pyongyang for 'shooting' a missing South Korean civilian as "shocking" and "unpardonable", according to state-run news agency Yonhap, citing a presidential Blue House official.
His comments came just hours after the South Korean Defence Ministry said in a statement that North Korea had fatally shot a missing South Korean official and burned his body, demanding that Pyongyang "provide an explanation and punish those responsible", Yonhap reported.
"North Korea found the man in its waters and committed an act of brutality by shooting at him and burning his body, according to our military's thorough analysis of diverse intelligence," the ministry said in a statement. "Our military strongly condemns such a brutal act and strongly urges the North to provide an explanation and punish those responsible".
The defence ministry also warned the DPRK that "all responsibilities for this incident lie with it".
Yonhap also reported, citing an unnamed Seoul offcial, that North Korea had "poured oil" over the body of the South Korean official aboard the patrol boat and set it aflame. South Korean intelligence reportedly suggested that North Korea had questioned the missing official on the patrol boat before killing him.
According to the unnamed official, the DPRK shot and killed the missing South Korean following an "order from superior authority".
The South Korean official that the DPRK is accused of killing and burning was affiliated with the Ministry of Oceans and Fisheries. He disappeared from an inspection near the island of Yeonpyeong on Monday.
Earlier, the South Korean defence ministry said it was looking for the missing official, noting that an investigation into his disappearance had been launched to check the facts that may be connected with North Korea in relation to the incident.
The two countries have tense relations despite several inter-Korean agreements. In June, the liaison office in North Korea's border city of Kaesong was demolished by the DPRK, with Pyongyang accusing Seoul of distributing anti-North Korean regime leaflets across the border via balloons.
