Nicolas Maduro, president of Venezuela, speaks during an event in Caracas, Venezuela, on Thursday, May 4, 2017. The South American nation has been riven by protests for weeks, and Maduro has called for a popular assembly to write a new constitution, a fresh attempt to consolidate control. Protests over the past month have resulted in at least 30 deaths, and opposition politicians have vowed to continue street actions. Photographer: Carlos Becerra/Bloomberg via Getty Images
