A customer pumps petrol into his vehicle in Caracas where people are queueing at gas stations on August 17, 2018 for the uncertainty about the price and availability of gasoline from Monday on, when the new currency with five fewer zeros starts circulating in Venezuela. - President Nicolas Maduro announced on August 13 that Venezuela's dirt-cheap fuel will be available only to people with a special government aid card that the opposition has denounced as a tool for controlling people. People who want to keep benefiting from subsidized gas prices in this oil-rich nation must register their vehicles by Friday using the so-called "carnet de la patria," or fatherland card, which provides access to government assistance.
