An anti-government protester wearing a Venezuelan flag picks up a tear gas canister fired by security forces trying to disperse an opposition demonstration, blocking it from reaching the Interior Ministry, in Caracas, Venezuela, Thursday, May 18, 2017. The protest in Caracas comes after a tumultuous 24 hours of looting and protests in the western state of Tachira that led the government to send in troop reinforcements, and after almost two months of unrest nationwide in which more than 40 people have been killed.
