Kidnappers release former Paraguay vice-president

Oscar Denis was taken by Paraguayan People's Army days after military killed two 11-year-old girls in unclear circumstances

Violence has intensified in Paraguay in the conflict between security forces and the Paraguayan People's Army (EPP) - a communist guerrilla movement active in the country's north-east.

A former vice-president was kidnapped by rebels days after the military killed two 11-year-old girls in unclear circumstances during an operation against the EPP, which human rights organisations described as a possible state crime".
