Supporters of former President Evo Morales clashed with police in the capital and in his stronghold towns as they demonstrated against conservative Sen. Jeanine Áñez declaring herself interim president, AP reports.The latest: Per AP, some of Morales' supporters ignited dynamite sticks, while others used "corrugated sheets of metal and wooden planks from construction sites" as weapons, as many chanted, "Now, civil war!" per AP. U.S. officials have welcomed Áñez's declaration.Amid violent clashes, Bolivia's self-declared interim president Jeanine Añez was sworn in and pledged to "revoke the conditions that turned us into a totalitarian country" pic.twitter.com/LKBPKHPibe— Bloomberg TicToc (@tictoc) November 14, 2019 The U.S. State Department ordered family members of U.S. government employees on Tuesday to leave Bolivia because of "widespread unrest" there following the resignation of President Evo Morales.The U.S. State Department urged Americans against travel to Bolivia and advised U.S. citizens in the country to "strongly consider departing as soon as they safely can do so."American officials "look forward" to working with Áñez as she and authorities "arrange free & fair elections as soon as possible," said Michael Kozak, acting assistant secretary for U.S. State Department's Bureau of Western Hemisphere Affairs, after she declared herself the interim president Tuesday night.Why it matters: Violence erupted in the country after the disputed Oct. 20 election, claimed by Morales. That escalated following his resignation Sunday. There were running street battles between pro- and anti-Morales protesters when he left Bolivia for the political asylum of Mexico Monday night. What he's saying: Morales said from Mexico that the country saved his life by granting him political asylum, but he said he's not done with politics, per AP, which reports him saying, "Let the whole world know that I won’t change ideology because of his coup."Background: The Organization of American States reported widespread electoral fraud. Morales promised fresh elections, but Gen. Williams Kaliman, commander of the armed forces, made a televised address in which he called on him to resign.The big picture: Per Axios' Dave Lawler, "Morales is a giant of recent Bolivian history. The country's first indigenous president, he's been credited with reducing poverty and overseeing strong economic growth.""But he also consolidated power over institutions and the media, and sought the presidency this year despite losing a referendum on whether he could do so."Go deeper: Bolivian Sen.
