Makiivka: Russia blames missile attack on soldiers' mobile phone use

Using banned phones allowed the enemy to locate its target,

But it is "already obvious" that the main cause of the attack was the presence and "mass use" of mobile phones by troops in range of Ukrainian weapons, despite this being banned, it added.

"This factor allowed the enemy to locate and determine the coordinates of the location of military personnel for a missile strike."

Officials found guilty in the investigation will be brought to justice, the statement added, and steps were being taken to prevent similar events in future.
