Demonstrators take cover during riots at a march to the state ombudsman's office in Caracas, Venezuela, May 29, 2017. Drawing inspiration from the Ukraine's 2013-14 revolt, Venezuela's young protesters are donning Viking-like shields in battles with security forces and eagerly watching a film on the Kiev uprising. The protesters use the shields to form walls, or even beat on them in unison, mimicking the Norsemen's battle cry. Fellow demonstrators cheer as the self-styled 'Resistance' members link arms to walk to the front lines and face off with National Guard troops and police.
