South Korea’s new defence minister on Saturday vowed to retaliate against North Korea if the communist nation carries out any future attacks.
Kim Kwan-jin, a retired army general, said “strong measures” would be taken if Pyongyang launched any further military assaults.
North Korea shelled a Southern island near the two countries’ disputed maritime border last week, killing four people and destroying several homes.
The shelling came after South Korea carried out naval exercises close to the border.
The South and the United States are set to stage further such exercises from Monday.
Pyongyang has said if those war games go ahead it will push tensions on the peninsula to an “uncontrollable extreme phase.”
