Bolivian soldiers filled the main plaza in La Paz and an armored vehicle breached a government palace on Wednesday afternoon before withdrawing in what government officials warned was a coup attempt by elements of the military.

“Today the country faces, once again, interests in toppling Bolivian democracy,” President Luis Arce, surrounded by his cabinet, said in a video statement. He said his government would stand “firm” against any coup attempt and called on the Bolivian people to mobilize “in favor of democracy.”
