Volunteer members of a primary care response team, huddle together during clashes with security forces at a rally against Venezuela's President Nicolas Maduro in Caracas, Venezuela, April 26, 2017. In Caracas, around 120 medicine students, doctors, and volunteers have revived a primary care response team first created during 2014's bout of anti-government protests. While they wear white helmets with a green cross, none wear flak jackets and some resort to wearing goggles to protect themselves from tear gas. Their equipment has nearly all been donated or bought by the volunteers themselves, and they've had to create makeshift neck braces from shoes, belts, and hats.
