Venezuelan President-elect Nicolas Maduro has accused the opposition of planning a coup against him after seven government supporters were killed in clashes over his disputed election victory.
Opposition leader Henrique Capriles wants a full recount of votes from Sunday's election.
Official results showed a narrow victory for Maduro, who is late socialist leader Hugo Chavez's hand-picked successor.
Opposition demonstrations outside electoral authority offices around the country passed off peacefully today.
Last night youths in Caracas and other cities blocked streets, burned tires and fought with police.
The authorities said the seven deaths included two people shot by opposition sympathisers while celebrating Mr Maduro's win in a middle-class area of the capital, and one person killed in an attack on a government-run clinic.
