Ukraine created a secret network of underground weapons factories - El Mundo

The Spanish Newspaper El Mundo, citing a source in the Ukrainian arms industry, has written that a network of hidden factories producing weapons has emerged in Ukraine since the start of the full-scale invasion. The source of El Mundo said that some of these factories are located underground, while others are hidden behind "huge scenery". El Mundo's source also noted that the issue of keeping the location of these plants secret is of particular concern to Kyiv, as "traitors" have already been found among the employees of the factories. It is noted that the construction of the hidden network of production facilities is being overseen by Oleksandr Kamyshin, the Minister of Strategic Industries.
