5. Chechnya's rebels Chechen terrorists have caused many terrorist attacks, suicide bombs, murders. But the grey past of the Chechens is no less than a tragedy.
In the 1990s, Russia launched two brutal wars to squash the dreams of Chechen independence, killing hundreds of thousands of people in the process.
The Chechen capital was bombed into smoking rubble, and impossible numbers of civilians were killed or displaced.
Chechens have been monitored by Russian secret agents, who frequently kidnap torture, mutilate, and murder dissenters, dumping their bodies into unmarked graves.
