Chechnya and Its Neighbors Suffer a Relapse, By Ellen Barry. The New York Times, August 30, 2009.
That case is difficult to make after the summer of 2009. Explosions and shootings have been a daily occurrence in the region all summer. Between June and August, 436 people have been killed, compared with 150 during the same months in 2008. And the number of attacks jumped to 452 from 265, according to statistics compiled by the Center for Strategic and International Studies, a private research group based in Washington.

The numbers do not fully capture what has happened. High-ranking officials have been strafed with machine-gun fire, targeted by snipers as they strolled out of restaurants or rammed with cars packed with explosives. A prominent human rights worker was snatched outside her apartment, killed and left on a roadside.

And suicide bombings, ominously, have returned to Chechnya after a pause of several years. Two militants blew themselves up Friday morning to escape capture, making it a total of three suicide bombings in the region in just the past week.
Interesting the speculation that Kadyrov might be replaced, and someone from Moscow brought in. That would unite the Chechen's against the external influence, and Moscow will have an even bigger problem.
