South Korea Claims North Korean Soldiers Unintentionally Fired Shots at DMZ Guard Post

Does anyone believe this excuse from the ROK military that the North Koreans unintentionally fired at a guard post because of the fog?:

 Several gunshots from North Korea hit a South Korean guard post inside the Demilitarized Zone (DMZ) on Sunday, prompting the South to fire back, but the North’s firings do not appear to have been intentional, an official said.

South Korean soldiers on guard duty at the unit in the central border town of Cheorwon heard gunshots at around 7:41 a.m. and found four bullet marks on a wall of the guard post, according to the Joint Chiefs of Staff.

In accordance with the response manual, the military then fired a total of 20 shots in response — 10 rounds each time — and issued broadcast warnings, it added. No casualties or damage to South Korean facilities were reported. 

It is not known if North Korea sustained any damage. 

“We also sent a notice to the North Korean side via the inter-Korean communication line at around 9:35 a.m., and called for its explanation,” a JCS officer said. 

North Korea has given no response yet. 

The military is closely looking into the incident to learn more details by analyzing pieces of evidence, including shells found at the scene, as well as the North’s motivations for the firing. It does not appear to be an intentional provocation, according to the officer. 

“It was quite foggy and the North Korean soldiers usually rotate shifts around that time,” the JCS officer said, adding that no unusual movements by the North’s military have been detected.

You can read more at the link, but the only way I can see the fog being a factor is that a North Korean soldier tripped over something and did not have his weapon on safe and it just happened to hit the ROK guard post. And this just happened to occur a day after Kim Jong-un made his first appearance in 20 days.
