Large-scale protests erupted across Venezuela as opposition supporters challenged President Maduro's imminent third-term inauguration.
Maria Corina Machado, a key opposition figure, made a high-profile return to public life, joining the demonstrations.
The opposition strongly contests the legitimacy of last year's election, citing irregularities and presenting alternative vote counts.
This political clash has international ramifications, with the US and other nations backing the opposition's challenge to Maduro's authority.
