After weeks of power cuts and limited access to water, tens of thousands of Venezuelans took to the streets on Saturday to back opposition leader Juan Guaido and protest against President Nicolas Maduro, who they accuse of wrecking the economy. Venezuelans, already suffering from hyperinflation and widespread shortages of food and medicine, say the crisis has worsened over the past month. That is when crippling nationwide power outages began to leave vast swaths of territory in the dark for days at a time, cutting off water supplies and cell phone service. Guaido, head of the opposition-controlled National Assembly and recognized as Venezuela's legitimate head of state by most Western nations, had called for rallies on Saturday to mark the start of what he has billed as a new wave of "definitive" protests to oust Maduro. Guaido invoked the constitution to assume an interim presidency in January, denouncing Maduro as a "usurper" for beginning a second term after a 2018 election widely considered fraudulent. Maduro, who retains the support of the military and allies including Russia and China, has derided Guaido as a US puppet and said he will face justice. In Caracas, thousands of opposition supporters assembled at a main rally point in the eastern El Marques district. Protesters said their homes had been without water for days and many had taken to drawing it from unsanitary pipes or streams running off the Avila mountain overlooking Caracas. "We have to get rid of this usurper, and we can't think about anything else," said Claudia Rueda, a 53-year-old homemaker at the protest. At one point, the crowd chanted, "The water has gone, power has gone, and now Maduro what's missing is that you go too." Two massive power outages in recent weeks led Maduro's government to cancel school classes and left many businesses shuttered. The resumption of services has been uneven, with cities such as San Cristobal, Valencia and Maracay still reporting intermittent blackouts. "We haven't just come to demand water and power. We've come to demand freedom and democracy," Guaido said at the Caracas rally, surrounded by a cheering crowd. "We can't let ourselves become used to this, we can't put up with it, we aren't going to let these crooks keep hold of our country." While no immediate protest-related violence was reported in Caracas, witnesses reported clashes between protesters and police in the steamy oil"I'm fed up. They hurt me, and though I was frightened, what it makes me most is angry," said Denis Fernandez, a 25-year-old who said he had been injured by a rubber bullet. Fernandez said his daughter had almost died from hepatitis a month ago, as hospitals had no supplies to treat her. When there is no electricity for air conditioning, he said he and his wife had taken to fanning their children at night to keep them cool. The ruling Socialist Party staged a rival march in Caracas' center on Saturday, with several thousand people, mostly state workers clad in red shirts and red baseball caps, banging drums and dancing salsa. Attendees Reuters spoke to echoed Maduro's statements that the power outages were due to attacks orchestrated by the US government. The opposition, along with power experts, blame the blackouts on the government's incompetence at maintaining the network and corrupt officials who have pocketed billions of dollars allocated to develop it. — Reuters
