At least 80 people were killed in northeast Colombia following failed attempts at peace talks with the National Liberation Army, a Colombian official said.

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.

The death toll from attacks by a rebel group in Colombia's Catatumbo region has risen to 60, the country's human rights office has said. Rival factions have been vying for control of the cocaine trade in the region - which sits near the border with Venezuela - for years.
