Clashes have again broken out in Bolivia as supporters of former President Evo Morales oppose the rule of the new interim leader.
Opposition senator Jeanine Áñez assumed the presidency amid a power vacuum and has vowed to hold elections soon.
Supporters of Mr Morales clashed with riot police, while lawmakers loyal to him sought to challenge the legitimacy of Ms Áñez’s appointment.
Mr Morales resigned on Sunday and has since fled to Mexico.
His resignation followed weeks of protests over a disputed presidential election result. He said he was forced to stand down but did so willingly “so there would be no more bloodshed”.
Ms Áñez’s appointment as interim leader has been endorsed by Bolivia’s Constitutional Court.
The latest demonstrations came as lawmakers loyal to Mr Morales sought to challenge Ms Áñez’s legitimacy.
They boycotted the session of congress called to formalise her claim to the presidency, preventing a quorum.
They have since been trying to hold new counter sessions.
Police reportedly blocked some lawmakers allied with Mr Morales from entering the country’s parliamentary assembly on Wednesday
