The North Korean military has fired its artillery at South Korean military loudspeakers in the western front across the Demilitarized Zone (DMZ).
Seoul's Defense Ministry said Thursday that it detected around 3:52 p.m. a trajectory of what is presumed to be a North Korean rocket artillery fired at Yeoncheon County in Gyeonggi Province, where the Army 28th Division is located.
In response, the South Korean military fired back 36 155-millimeter shells around 5 p.m. to where the attack originated.
No damage has been confirmed on the South Korean military facilities, including its military loudspeakers that are used for propaganda broadcasts. Eleven South Korean military loudspeakers are located two kilometers away from North Korean guard posts.
A military official said that the North Korean shell is believed to have landed on a mountain.
North Korea had been strengthening training for an attack on the South Korean military loudspeakers that are recently reactivated for propaganda broadcasts.
South Korea has been heightening its military vigilance after the North was spotted leaving the gun embrasures open in their general outposts along the demarcation line.
The attack comes after South Korea resumed its psychological warfare operations on August 10 in the wake of the North's land mine explosions that injured two South Korean soldiers on August 4.
The broadcasts were suspended in June 2004 under an inter-Korean agreement. South Korea set up facilities to resume the broadcasts after the Cheonan incident in 2010, but had not resumed broadcasting.
