The explosions occurred on South Korea's side of the Demilitarised Zone (DMZ), a buffer zone separating the two Koreas. Three South Korean personnel were injured in the blasts. On Tuesday, South Korea said the explosions were 'highly likely' from North Korean mines and vowed to take 'corresponding measures' for what it described as a violation of the 1953 armistice. South Korean Defence Minister Kang Shin-chul said the blasts were a 'clear' breach of the armistice, which halted active combat in the Korean War.
North Korea has strongly rejected the allegations. Kim Yo Jong, in a statement published in state media on Wednesday, accused South Korea of 'cooking up' the claims for 'political and military provocation'. She denied suggestions that North Korean personnel crossed the border to lay the mines, calling it 'a deliberate and planned strained assertion to shift the responsibility for escalating tension' to North Korea. Kim also warned the South to be 'prepared for paying price for the farce of their own making'.
South Korea maintains that the mines were planted by Pyongyang to fortify its border. In a statement on Wednesday, Seoul called for North Korea to apologise for the blast and put an immediate stop to such fortification activities along the border.
