Earlier in the day, military units led by General Juan Jose Zuniga, recently stripped of his military command, had gathered in the central Plaza Murillo square, home to the presidential palace and Congress. A Reuters witness saw an armored vehicle ram a door of the presidential palace and soldiers rush in.
Tensions have been building in Bolivia ahead of general elections in 2025, with leftist ex-President Evo Morales planning to run against former ally Arce, creating a major rift in the ruling socialist party and wider political uncertainty.
Many do not want a return of Morales, who governed from 2006-2019 when he was ousted amid widespread protests and replaced by an interim conservative government. Arce then won election in 2020.
Zuniga said recently that Morales should not be able to return as president and threatened to block him if he attempted to, which led Arce to remove Zuniga from his post.
