Evo Morales, the former Bolivian president, said on Sunday a car he was travelling in had been shot at in what he condemned as an attempt on his life.
A video he posted to social media appeared to show at least two bullet holes in the windscreen of a car in the front seat of which Morales was sitting.
In a statement, Morales's Movement for Socialism (Mas) party said men in black had fired on the vehicle when it passed by a military barracks. The party said it held President Luis Arce's government responsible.
Arce condemned violence in politics and pledged an investigation.
