Led by a top general vowing to “restore democracy,” armored vehicles rammed the doors of Bolivia’s government palace Wednesday in what the president called a coup attempt, then quickly retreated – the latest crisis in the South American country facing a political battle and an economic crisis. Within hours, the nation of 12 million people saw a rapidly moving scenario in which the troops seemed to take control of the government of President Luis Arce. He vowed to stand firm and named a new army commander, who immediately ordered the troops to stand down. Soon the soldiers pulled back, along with a line of military vehicles, ending the rebellion after just three hours. Hundreds of Arce´s supporters then rushed the square outside the palace, waving Bolivian flags, singing the national anthem and cheering.
