Sources of British special services have reported that the Russian secret services threatened to hurt the families of chiefs of the Wagner Private Military Company (PMC) before Yevgeny Prigozhin, the owner and leader of the Wagner PMC, stopped his offensive on Moscow.
It seemed like a sudden change in marching orders, so the chiefs probably didn’t have enough notice to have families moved to someplace safer. Now that Prigozhin has backed off, for whatever deal was made, he probably doesn’t have long before he dies of poison or falling out a window (if it hasn’t happened already).
