August 30 Bolshoi Gorod has a very good piece on Beslan by Yekaterina Krongauz - Krest Beslana, in Russian.
September issue of the Russian Esquire has "The School" by C.J. Chivers in Russian, translated by Artyom Osokin.
In English and not on Beslan, but by C.J. Chivers, a piece on kadyrovtsy and torture in Chechnya, with videos attached, in the New York Times - In Chechen’s Humiliation, Questions on Rule of Law:
[...] Few people have yet compared the current disorder with the end of the brief period of Chechen autonomy, in the late 1990’s, when rebels and foreign Islamic mercenaries operated terrorist training camps in the forests, and when Islamic courts sentenced criminals to execution by firing squads, which were broadcast on Chechen television news. But Mr. Kadyrov’s police and security forces, known as kadyrovsty, are staffed mostly with uneducated young men, some of whom have been fighting for years, including many former rebels who have changed sides.
Recent videos of their conduct, provided to The New York Times by outraged Chechens, show an unsettling pattern.
What has made several recent cases different is that many of the kadyrovsty, unsophisticated gunmen who have had little contact with the world beyond Chechnya, have acquired cellphones with small video cameras and have casually, even gleefully, recorded their own crimes.
The video sequences are then shared, multiplying as they swiftly pass from phone to phone. [...]
These three pieces alone should make the world collapse, it seems, but no, life goes on as usual.
