The South Korean military has issued an alert on the country's western border following the defense ministry's announcement Monday that North Korea was behind the recent landmine explosions that severely wounded two South Korean soldiers.
Defense Minister Han Min-koo says the South Korean military will intensify its operations along the demilitarized zone.
"We will not be daunted. We will conduct operations to seize control at the DMZ."
Han also confirmed that South Korea on Monday afternoon resumed its previous policy of blasting anti-Pyongyang propaganda across the inter-Korean border, and is reviewing other follow-up steps it can take.
This marks the first time South Korea has cranked up the loudspeakers since the two Koreas agreed that Seoul would stop in June 2004.
North Korea has yet to issue a response since the broadcasts resumed, but in 2010 when the South said it would restart the speakers in the wake of North Korea's sinking of a South Korean warship, Pyongyang threatened to fire on the speakers.
South Korea's defense ministry said on Tuesday that it will counter and destroy the source of the attack if the North decides to fire on the loudspeakers.
Responding to the latest spike in inter-Korean tensions, UN Secretary General Ban Ki-moon urged North Korea to respect the armistice agreement and engage in dialogue to ease tensions on the peninsula..
In regards to a probe into the landmine blasts, military officials say North Korea may have planted the mines ahead of a possible incursion into the South.
The North might have also been trying to derail an annual round of military drills between Seoul and Washington slated for next week.
