Venezuelan security forces have carried out hundreds of arbitrary killings under the guise of fighting crime, the UN’s human rights body says.
In a report, it cites “shocking” accounts of young men being killed during operations, often in poor neighborhoods, between 2015 and 2017.
The UN’s human rights chief said no-one was being held to account, suggesting the rule of law was “virtually absent”.
Venezuela has in the past dismissed human rights allegations as “lies”.
The country is going through a protracted political and economic crisis.
Venezuela has the world’s largest proven oil reserves. When socialist President Hugo Chávez was in power, from 1999 until his death in 2013, he used oil money to finance social programs.
But the opposition says much of the income was lost to mismanagement, patronage, and corruption.
Critics accuse Mr Chavez’s successor, President Nicolás Maduro, of using increasingly authoritarian tactics as the economy collapsed, prompting hundreds of thousands of people to flee abroad.
Last year dozens of protesters were killed in clashes during protests against hyperinflation and food shortages.
Mr Maduro was re-elected in May, in a poll boycotted by the opposition and criticized by the UN and other international bodies.
The UN Human Rights Council alleges that extra-judicial killings were carried out by officers involved with the Operations for the Liberation of the People, ostensibly a crime-reduction initiative.
These officers may have killed more than 500 people between July 2015 and March 2017 as a way to showcase crime-reduction results, it says. They are alleged to have faked evidence to make it look as though the victims died in exchanges of fire.
UN investigators have been denied access to Venezuela. They made their findings from interviews with about 150 witnesses and victims contacted through “internet-based technologies”, the report says.
A number of interview with exiles were also held in Geneva, it adds. Some of the other evidence comes from former Attorney General Luisa Ortega. She was fired by Mr Maduro last year and went into exile.
The report says that under her replacement, investigations into allegations of abuses have virtually stopped.
The UN High Commissioner for Human Rights, Zeid Ra’ad Al Hussein accused Venezuela of failing to acknowledge the depth of its crisis.
“When a box of hypertension pills costs more than the monthly minimum wage and baby milk formula more than two months’ salary, but protesting against such an impossible situation can land you in jail, the extreme injustice of it all is stark,” he added.
Mr Hussein suggested the International Criminal Court could become involved.
Earlier this week the US quit the UN Human Rights Council, having previously criticized the body for failing to act against a number of countries, including Venezuela.
