As it turns out the North Koreans did not fire artillery at the loudspeaker on the ROK side of the DMZ and instead used an anti-aircraft weapon:
The two Koreas traded fire on Thursday after the North launched artillery shells apparently targeting propaganda loudspeakers installed across the border, threatening additional military action against the broadcasts and further heightening tension on the peninsula.
The North fired a 14.5-milimeter anti-aircraft gun once at around 3:53 p.m. at a town in Yeoncheon County, Gyeonggi Province, and then a 76.2-mm direct fire weapon “several times” at 4:15 p.m. within the Demilitarized Zone, military officials here said. Shortly after detection, the Army discharged a 155-milimeter self-propelled gun at 5:04 p.m.
The Army reported no damage. Casualties in the North were not immediately known.
Coincidentally with the exchange of fire, Pyongyang sent two separate letters to the South, calling for a withdrawal of the loudspeakers and threatening military action.
In the letter sent from the General Staff of the North Korean People’s Army to South Korea’s Defense Ministry through a border telephone channel at around 4:50 p.m., Pyongyang warned that it would initiate “military action” unless Seoul stops the propaganda broadcasts within 48 hours from 5 p.m.
In a separate letter by Kim Yang-gon, director of the United Front Department in charge of cross-border affairs, to National Security Office chief Kim Kwan-jin, Pyongyang said the broadcasts constitute a “declaration of war” but it is willing to resolve the current situation and “open a way out for the improvement of the relationship.”
Seoul said it has no plan to dismantle the speakers at this point. (………….)
The North’s anti-aircraft gun ammunition appeared to have hit an uninhabited hill located several kilometers away from a loudspeaker set, an official at Seoul’s Defense Ministry said. Yet the North did not appear to have aimed at the equipment, he noted, without elaborating.
“We detected signs that the North Korean military staged two rounds of firearm provocation in the southern part of the Military Demarcation Line, and fired dozens of rounds of a 155-millimeter self-propelled gun as warning shots,” Joint Chief of Staff spokesman Col. Jeon Ha-kyu said at a news briefing. [Korea Herald]
