The misfortune of the four garlic pickers was to have unwittingly strayed into a "counter-insurgency operation" conducted by Russian forces in the densely wooded border between Chechnya and Ingushetia. The soldiers, apparently looking for militant rebels who are waging their own violent campaign against the Russian state, came across the unarmed group, brutally killing them amid the picturesque massif of low hills.Normally this atrocity on a cold day in February would have raised barely a ripple of attention had it not been for the terrible events in Moscow this week. In a video address on Thursday, Chechnya's chief insurgent leader, Doku Umarov, said Monday's suicide attacks on the Russian capital's metro were in revenge for the killings of the garlic pickers near the Ingush village of Arshaty. He claimed federal security service (FSB) commandos had used knives to mutilate their bodies of the dead boys.
