A global human rights watchdog on Wednesday implicated Venezuelan security forces and pro-government armed groups in killings that occurred during the protests that followed the country’s disputed July presidential election.

Human Rights Watch, in a report detailing repressive measures the government unleashed after the vote, asserted that credible evidence gathered and analyzed by researchers, forensic pathologists and arms experts ties Venezuela’s national guard and national police to some of the 24 killings that took place as people protested the outcome of the election. The organization also concluded that violent gangs aligned with the ruling party also “appear to be responsible” in some of the deaths.

Twenty-three of those killed were protesters or bystanders and one was a member of the Bolivarian National Guard.
