South Korea fired tens of artillery rounds toward North Korea on Thursday after the North launched shells to protest South Korea’s anti-Pyongyang propaganda broadcasts along the border, as tension escalated on the peninsula.
North Korea did not return fire but later warned Seoul in a letter that it would take military action if the South did not stop the loudspeaker broadcasts within 48 hours, the South’s defense ministry said.
In a separate letter, Pyongyang said it was willing to offer an opening to resolve the conflict even though it considers the broadcasts a declaration of war, South Korea’s Unification Ministry said.
A South Korean military official said the broadcasts, which began on Aug. 10, would continue.
South Korea said the North fired a 14.5 mm anti-aircraft shell at 3:52 p.m. (0652 GMT), then fired multiple shells from a 76.2 mm direct fire weapon at 4:15 p.m.
No damage or injuries were reported in the South.
South Korean President Park Geun-hye told top defense officials to “react firmly” to North Korean provocations, a spokesman quoted her as saying.
