The death of a 15-year-old boy brought the toll from weeks of protests in Venezuela to 43 — a dark milestone that matched the number killed in the last comparable wave of unrest, in 2014.
Looting and attacks against security installations erupted overnight in the state of Tachira, which borders Colombia, authorities said. The state prosecution service said on Twitter the boy was killed “during a demonstration” there.
“I have ordered the transfer of 2,000 guards and 600 special operations troops” to Tachira, Defense Minister Vladimir Padrino Lopez said on state television channel VTV.
