A view of a cemetery, where people including militants killed by security forces are buried, on the suburbs of Makhachkala, October 1, 2013. Ahead of the Sochi Olympics in February, Russia is taking saliva samples from religiously conservative Muslim women, according to locals in the North Caucasus, gathering DNA so authorities can identify the body parts if any become suicide bombers. The move coincides with a drive by President Vladimir Putin to crack down on an Islamist insurgency in Dagestan, a province in the foothills of the Caucasus Mountains east of the Winter Games sites in Sochi.
