Venezuela's Guaido urges troops to rise against Maduro, violence breaks out

Venezuelan opposition leader Juan Guaido on Tuesday called for a military uprising to oust President Nicolas Maduro and violence broke out at anti-government protests as the country hit a new crisis point after years of political and economic chaos. Several dozen armed troops accompanying Guaido clashed with soldiers supporting Maduro at a rally outside the La Carlota air base in Caracas, but the incident fizzled out and did not appear to be part of an immediate attempt by the opposition to take power through military force. Guaido, in a video posted on Twitter earlier on Tuesday, wrote that he had begun the "final phase" of his campaign to topple Maduro, calling on Venezuelans and the armed forces to back him ahead of May Day mass street protests planned for Wednesday.
