Venezuela’s beleaguered President Nicolas Maduro on Monday called for a new constitution, to be written by a “people’s” body circumventing the opposition-held Congress. The decree was to “block the fascist coup” threatening the country, he told thousands of supporters in Caracas at a May Day rally. / AFP/RSS PHOTO / Federico PARRA
