The country's president, Luis Arce, warned that an "irregular" deployment of troops had taken place and called for "democracy to be respected" on X as Bolivian TV showed two tanks and a number of soldiers in front of the government palace in La Paz.

Video on Bolivian TV showed Mr Acre confronting the general commander of the army, Juan Jose Zuniga, in the palace hallway, telling him: "I am your captain, and I order you to withdraw your soldiers, and I will not allow this insubordination."

Before entering the building Mr Zuniga told journalists in the plaza: "Surely soon there will be a new cabinet of ministers; our country, our state cannot go on like this."

Mr Zuniga said he recognises President Arce as commander in chief "for now".

Former Bolivian president Evo Morales denounced the movement of the military in the Murillo square outside the palace in a post on X, calling it a coup "in the making".

Mr Zuniga earlier confirmed the movement of uniformed officers and said: "We are upset by the affront, enough is enough."

He spoke on TV of "attacks on democracy" without elaborating.
