" … 15 minutes ago [Venezuelan] National Guard Sergeant San Clemente Barrios Neomar was killed by a sniper in Los Castores," Saab wrote on Twitter late on Wednesday.
Earlier on Wednesday, local media reported that at least two people were killed in mass protests against Venezuelan President Nicolas Maduro, one of them in the capital Caracas.
Henrique Capriles, a Venezuelan opposition leader, announced on Wednesday that major anti-government protests were also planned for Thursday.
The most recent anti-government demonstrations started in Venezuela at the beginning of April, after the country’s Supreme Court attempted to take on the legislative functions of the country's National Assembly, controlled by the opposition. The court's ruling was later reversed, however, tensions remained in the country, which is suffering from a severe economic crisis.
The opposition has blamed the Venezuelan government for the deaths of people during the recent demonstrations.
