A medical volunteer helps an injured anti-government protester at the site of clashes with riot police in Kiev January 22, 2014. Injured anti-government protesters fearing arrest are shunning Kiev's hospitals and choosing to undergo operations in field clinics run by an army of volunteer doctors. Since clashes between activists and security forces worsened last week, doctors have faced more serious injuries, colds and frostbite from the seering cold escalating to flesh wounds, gas burns and concussions from the violence.
