 In what was the most dramatic day in Bolivian politics in years, an attempted insurrection by a rebel group of the armed forces was successfully launched in La Paz, but was swiftly brought to an end. With troops surrounding the doors of the National Palace and other government buildings, the man leading the apparent coup, the head of the army, General Juan José Zúñiga, said he would continue to recognize the president, Luis Arce, for the time being, but not the cabinet, which he said he expected to be replaced.
