BOGOTÁ, Colombia — More than 80 people were killed in the country’s northeast over the weekend following the government’s failed attempts to hold peace talks with the National Liberation Army, a Colombian official said. [time-brightcove not-tgx=”true”] Twenty others were injured in the violence that has forced thousands to flee as Colombia’s army scrambled to evacuate people on Sunday, according to William Villamizar, governor of North Santander, where many of the killings took place. Among the victims are community leader Carmelo Guerrero and seven people who sought to sign a peace deal, according to a report that a government ombudsman agency released late Saturday. Officials said the attacks happened in several towns located in the Catatumbo region near the border with Venezuela, with at least three people who were part of the peace talks being kidnapped. Thousands of people are fleeing the area, with some hiding in the nearby lush mountains or seeking help at government shelters. “We were caught in the crossfire,” said Juan Gutiérrez, who fled with his family to a temporary shelter in Tibú after they were forced to leave behind their animals and belongings.
