Bolivia’s army chief was arrested Wednesday after sending soldiers and tanks to take up position in front of government buildings in what President Luis Arce called an attempted coup.

The troops and tanks entered Plaza Murillo, a historic square where the presidency and Congress are situated, in the afternoon, prompting global condemnation of an attack on democracy.

One of the tanks tried to break down a metal door of the presidential palace.

Surrounded by soldiers and eight tanks, the now-dismissed army chief General Juan Jose Zuniga said the “armed forces intend to restructure democracy, to make it a true democracy and not one run by the same few people for 30, 40 years.”

Shortly thereafter, AFP reporters saw soldiers and tanks pulling back from the square. The uprising lasted about five hours.
