Roughly one person is being lynched in crisis-ridden Venezuela every three days as frustrated residents take revenge on suspected criminals, a monitoring group said on Wednesday.

The Venezuelan Observatory of Violence (OVV), which monitors crime, said mob killings have become a generalized phenomenon across the country, with 126 deaths reported in 2016 versus 20 last year.

"Due to being repeated victims of crime for more than a decade, and the feeling of not being protected, many people have decided to take justice into their own hands," the OVV said in its latest annual report.
