Kim Jong-un allegedly had engineers executed over a collapsed building

Pyongyang - The North Korean leader Kim Jong-un reportedly had a firing squad shoot engineers who were working on the construction of a residential building that collapsed last week. An estimated 500 people died in the rubble. This was reported today by the news site news.com.au, stating that it is difficult to verify such reports from communist North Korea.
The 23-story building collapsed in Pyongyang, and local residents then received a rarely seen public apology from the North Korean regime. Media reported that Kim Jong-un "was awake all night with painful feelings after learning about the accident."
According to information first reported by the Japanese press, Kim Jong-un had four engineers executed and sent a military officer who was supervising the project to a labor camp. Similar reports are very difficult to verify given the closed nature of the North Korean regime, and there have been instances where people allegedly executed have reappeared in public in North Korea.
North Korea has not stated what caused the collapse of the unfinished building, into which people had already moved. However, a lack of construction materials may have played a role. It is reported that construction workers in North Korea often steal materials such as steel or cement and sell them on the black market.
