Venezuelan President Nicolas Maduro has fled from the Midaflores Palace as citizens now attempt to occupy it.
Security forces in Venezuela had earlier fired tear gas and rubber bullets at people protesting Sunday’s disputed election result.
Thousands of people descended on central Caracas on Monday evening, some walking for miles from slums on the mountains surrounding the city, towards the presidential palace.
Protests erupted in the Venezuelan capital the day after President Nicolás Maduro claimed victory.
The opposition has disputed Mr Maduro's declaration as fraudulent, saying that after reviewing 73.2% of the voting tallies, it was clear that its candidate, Edmundo González, had won convincingly.
