Two more people have been killed in Venezuela, in rival protests both for and against the government of President Nicolas Maduro.
The violence raised the death toll to 23 in three weeks of protests.
Ombudsman Tarek Saab said several others were seriously injured and "between life and death".
The latest protests were sparked by the decision by the Supreme Court to take over the powers of the opposition-dominated National Assembly.
The court's reversal of the ruling was not enough to stop a wave of demonstrations.
On Monday a man was shot dead in a pro-government demonstration in the city of Merida and another man was killed in the nearby town of Barinas.
Merida state Governor Henrique Capriles, one of Venezuela's main opposition leaders, tweeted that "paramilitary groups" were responsible for the killings.
12 people have been killed in pro- and anti-government demonstrations this month so far.
Another 11 people died on Friday when a bakery was looted in Caracas.
